0:00:03 > 0:00:05Not the shrinking cap, Grandpa!
0:00:06 > 0:00:07Catch me if you can!
0:00:09 > 0:00:11Grandpa!
0:00:17 > 0:00:19No! Be careful!
0:00:25 > 0:00:26Grandpa, stop!
0:00:35 > 0:00:37Whoa...
0:00:47 > 0:00:51'Today we were playing Captain Dumbletwit Let's Pretend.
0:00:51 > 0:00:54'Grandpa was wearing his costume.'
0:00:54 > 0:00:58Captain Dumbletwit, off to save the universe!
0:00:58 > 0:01:00'Mum came down in a panic.'
0:01:00 > 0:01:03I'm in a bit of a panic.
0:01:03 > 0:01:06Jason, Jemima, can you tidy up in here?
0:01:06 > 0:01:08Our special visitors are due any moment.
0:01:08 > 0:01:13'The SPECIAL visitors were Grandpa's old friend Gilbert
0:01:13 > 0:01:15'and his granddaughter Martha.'
0:01:15 > 0:01:18Oh, you're going to love Granddad Gilbert,
0:01:18 > 0:01:20he's got a great imagination.
0:01:20 > 0:01:23Will he play Captain Dumbletwit?
0:01:23 > 0:01:27Oh, for sure! We'll be able to act out space missions.
0:01:27 > 0:01:31If Dumbletwit can do it, so can you!
0:01:31 > 0:01:34'Little did we know it was going to be...'
0:01:39 > 0:01:43I can't wait to show Granddad Gilbert my treasure chest.
0:01:43 > 0:01:46We used to play with these toys.
0:01:46 > 0:01:50We were best friends, we even had a special greeting.
0:01:50 > 0:01:52# Teeny beeny zac-ar-ac-ah big bong what-ah-cracker
0:01:52 > 0:01:55# Slippah slappah pop-a-lo-pah om pom boof. #
0:01:55 > 0:01:57DOORBELL RINGS
0:01:57 > 0:02:01'Granddad Gilbert and his granddaughter Martha
0:02:01 > 0:02:02'were at the door.'
0:02:02 > 0:02:06Martha! Gilbert! How wonderful to see you!
0:02:06 > 0:02:08# Teeny beeny zac-ar-ac-ah big bong what-ah-cracker
0:02:08 > 0:02:10# Slippah slappah pop-a-lo-pah om pom boof. #
0:02:10 > 0:02:12LAUGHTER
0:02:12 > 0:02:16- Are you all right? - Well, it's our greeting, our...
0:02:16 > 0:02:17Don't you remember it?
0:02:17 > 0:02:19I can't say I do.
0:02:19 > 0:02:21Do you always dress like that?
0:02:21 > 0:02:26What? This? Oh, I'm being Captain Dumbletwit for the kids.
0:02:26 > 0:02:27I made the costume,
0:02:27 > 0:02:31- we couldn't find a big one. - I don't suppose you could.
0:02:31 > 0:02:34Come along, everyone. Come on, Martha.
0:02:35 > 0:02:39'Grandpa hadn't seen Gilbert for years and years.'
0:02:44 > 0:02:46'There was a long pause.
0:02:46 > 0:02:50'Nobody knew what to say. Then, I thought of something.'
0:02:50 > 0:02:54Grandpa told us about the games you played, he's got his toys!
0:02:54 > 0:02:58Hello, Gilbert. Monkey Albert! You must remember Monkey Albert?
0:02:58 > 0:03:00Can't say that I do.
0:03:00 > 0:03:06'There was another even LONGER pause. Grandpa was looking fed up.
0:03:06 > 0:03:11'Granddad Gilbert was fed up. Then, Jemima thought of something.'
0:03:11 > 0:03:16- Do you like Captain Dumbletwit, Martha?- Yes! It's REALLY funny.
0:03:16 > 0:03:21- Why don't we play the Dumbletwit board game?- I don't like board games.
0:03:21 > 0:03:24You can play if you like, but not here - it's noisy.
0:03:24 > 0:03:30'So, Jemima and Martha went upstairs and I went to fetch the board game.
0:03:30 > 0:03:34You must look at our garden. You can give me ideas.
0:03:34 > 0:03:36I doubt it.
0:03:36 > 0:03:40'So, Mum took Granddad Gilbert out to show him the garden.'
0:03:42 > 0:03:45Ideas, huh! Gilbert used to be full of ideas!
0:03:45 > 0:03:48But now he's lost his imagination.
0:03:48 > 0:03:51We are going to try and help to get it back again.
0:03:51 > 0:03:54There's only one way to do it.
0:03:54 > 0:03:57Not the shrinking cap, Grandpa!
0:03:58 > 0:04:00Catch me if you can!
0:04:00 > 0:04:03'You know what it's like when Grandpa shrinks.
0:04:03 > 0:04:06'He gets up to all sorts of things -
0:04:06 > 0:04:08'he can ride off in my car,
0:04:08 > 0:04:10'he can fly off in my plane.
0:04:10 > 0:04:13'What would he get up to dressed as Captain Dumbletwit?'
0:04:13 > 0:04:15Come on!
0:04:15 > 0:04:18'Mum came back in with Granddad Gilbert.'
0:04:18 > 0:04:22Where's Grandpa? He must have gone for a lie down.
0:04:22 > 0:04:24When I've come all this way to see him?
0:04:24 > 0:04:30He has a lot of lie downs, especially when we have visitors.
0:04:30 > 0:04:32Oh, well. I can finish my crossword.
0:04:32 > 0:04:36Great! I'll make a start on the lunch.
0:04:36 > 0:04:39Sausage, beans and jelly all right?
0:04:40 > 0:04:43'Of course, Grandpa wasn't laying down.
0:04:43 > 0:04:47'He was standing right above Granddad Gilbert.
0:04:47 > 0:04:49'And Grandpa, being Grandpa...
0:04:49 > 0:04:52'was bound to have a plan.
0:04:52 > 0:04:55'While Granddad Gilbert was busy doing his crossword,
0:04:55 > 0:04:59'Grandpa crawled towards the Doojit puppet.
0:05:00 > 0:05:02'I had no idea this was going on,
0:05:02 > 0:05:06'because I was having fun with Jemima and Martha.
0:05:06 > 0:05:10'There was certainly no fun going on downstairs.
0:05:10 > 0:05:13'But Grandpa was about to change that.
0:05:13 > 0:05:16'He had got right inside the Doojit puppet.
0:05:16 > 0:05:18'I checked on Grandpa,
0:05:18 > 0:05:21'I tiptoed to the bottom of the stairs.'
0:05:21 > 0:05:24I'm Doojit! Captain Dumbletwit's alien pet.
0:05:24 > 0:05:28Yes, very funny, Jason. Go away, I'm finishing my crossword.
0:05:28 > 0:05:32'Granddad Gilbert thought it was me!
0:05:32 > 0:05:35'I had to get Grandpa out of Doojit.'
0:05:35 > 0:05:38Give Captain Dumbletwit his spaceship.
0:05:38 > 0:05:40'But I was too late.'
0:05:40 > 0:05:43Oh, do stop this nonsense.
0:05:43 > 0:05:45'This was a disaster!
0:05:45 > 0:05:47'Grandpa was stuck inside Doojit.
0:05:47 > 0:05:51'Any second, Granddad Gilbert was going to find him.
0:05:51 > 0:05:52'I had to do something.'
0:05:52 > 0:05:54Let me go! Let me go!
0:05:54 > 0:05:55I knew it was you.
0:05:55 > 0:05:57Now stop it. Really.
0:05:57 > 0:06:02'The good news was that Granddad Gilbert hadn't seen Grandpa.
0:06:02 > 0:06:06'The bad news was that he'd shut him in the treasure chest.
0:06:06 > 0:06:08'I had to get him out.'
0:06:09 > 0:06:10Oh, no, you don't.
0:06:10 > 0:06:12Upstairs with you, go on.
0:06:12 > 0:06:17'There was nothing I could do, I was worried about Grandpa.
0:06:17 > 0:06:21'But Grandpa, being Grandpa, was bound to have a plan.
0:06:22 > 0:06:27I've run out of sausages, beans AND jelly! Ha-ha! Won't be long.
0:06:27 > 0:06:30'I was right, Grandpa DID have a plan!
0:06:30 > 0:06:33'And now Mum had gone, he could put it into action.
0:06:33 > 0:06:35Let me out!
0:06:35 > 0:06:38KNOCKING Let me out!
0:06:38 > 0:06:40KNOCKING
0:06:46 > 0:06:48Please let me out!
0:06:48 > 0:06:49Jason!
0:06:49 > 0:06:52Please let me out!
0:06:54 > 0:06:59Thanks! Oh. Was getting mighty stuffy in there.
0:06:59 > 0:07:02Name's Dumbletwit, Captain Dumbletwit.
0:07:02 > 0:07:05'Granddad Gilbert thought Grandpa was a toy!'
0:07:05 > 0:07:07What an amazing toy!
0:07:07 > 0:07:09'Then, he tried to grab him.
0:07:09 > 0:07:13'Grandpa ran and Granddad Gilbert ran after him!'
0:07:14 > 0:07:19'He watched Grandpa run along the shelf and peep out.'
0:07:23 > 0:07:25'Then, he lost him!'
0:07:28 > 0:07:31'Grandpa jumped onto the chair.'
0:07:31 > 0:07:34Stop. Come back. Come here!
0:07:34 > 0:07:38'But Grandpa had other ideas.
0:07:38 > 0:07:41'The lights on Captain Dumbletwit's spaceship
0:07:41 > 0:07:43'started to flicker.'
0:07:44 > 0:07:45Oh!
0:07:45 > 0:07:48'Grandpa had climbed inside.
0:07:48 > 0:07:52'When Grandpa is small, he can use his magic to make my toys go.
0:07:52 > 0:07:56'Sometimes it's my plane, sometimes it's my car...
0:07:56 > 0:07:59'and now it was my spaceship!'
0:08:02 > 0:08:07'Granddad Gilbert couldn't believe his eyes!
0:08:07 > 0:08:10'This time Grandpa had gone too far
0:08:10 > 0:08:13'and he was about to go even further.'
0:08:19 > 0:08:23I've never seen anything like it in my life.
0:08:23 > 0:08:24Who are you?
0:08:24 > 0:08:25And WHAT are you?
0:08:25 > 0:08:29The name's Dumbletwit, Captain Dumbletwit.
0:08:29 > 0:08:32I'm on a mission to give you back your imagination.
0:08:32 > 0:08:34My imagination?
0:08:34 > 0:08:35Yes.
0:08:40 > 0:08:45I wouldn't be the space hero I am if I didn't have an imagination.
0:08:45 > 0:08:46And you need one too.
0:08:46 > 0:08:48Do I?
0:08:50 > 0:08:51Why?
0:08:51 > 0:08:55To play with your granddaughter and to have fun.
0:08:55 > 0:08:59I'm too old to have fun, I've forgotten how.
0:08:59 > 0:09:03Nonsense! Just remember what it was like when you were a child,
0:09:03 > 0:09:05you knew how to have fun then.
0:09:05 > 0:09:08Yes. Yes, I suppose I did.
0:09:08 > 0:09:13Ha! My best friends and I did play some wonderful games.
0:09:15 > 0:09:18'And he started to remember all the fun
0:09:18 > 0:09:20he and Grandpa had had together.'
0:09:20 > 0:09:23Well... We'd pretend to be knights
0:09:23 > 0:09:29or explorers in the jungle.
0:09:29 > 0:09:32We even made up our own funny greeting.
0:09:32 > 0:09:35# Teeny beeny zac-ar-ac-ah big bong what-ah-cracker
0:09:35 > 0:09:39# Slippah slappah pop-a-lo-pah om pom boof. #
0:09:39 > 0:09:44See! Your imagination is coming back to you already.
0:09:44 > 0:09:45What did I tell you?
0:09:45 > 0:09:48If Dumbletwit can do it, so can you.
0:09:48 > 0:09:51Now you're ready to go and play with Martha.
0:09:51 > 0:09:55Yes. Yes, I will. Thank you, Captain Dumbletwit.
0:09:56 > 0:09:57Oh!
0:09:58 > 0:10:02You know, you're not as dumb as you look.
0:10:04 > 0:10:06Martha!
0:10:06 > 0:10:09- Mission accomplished.- Martha!
0:10:09 > 0:10:12'Granddad Gilbert rushed upstairs.
0:10:12 > 0:10:15'and Grandpa rushed to take his costume off.'
0:10:15 > 0:10:18You'll never believe what I've just seen!
0:10:18 > 0:10:20Captain Dumbletwit!
0:10:20 > 0:10:24He was flying in his spaceship and he even spoke to me.
0:10:24 > 0:10:27"If Dumbletwit can do it, so can you."
0:10:27 > 0:10:29That's what he said. He's right.
0:10:29 > 0:10:33Em... I'll think I'll just go see if lunch is ready.
0:10:33 > 0:10:36'I ran downstairs as Grandpa took off his cap
0:10:36 > 0:10:38'and came back to normal.'
0:10:38 > 0:10:40What have you been up to?
0:10:40 > 0:10:44I've been on a mission. It was tough, but I succeeded.
0:10:44 > 0:10:47And thank you for rescuing me from Doojit.
0:10:47 > 0:10:48I did what I could.
0:10:48 > 0:10:50- Teamwork, eh?- Teamwork!
0:10:50 > 0:10:53'Soon Grandpa was back in his normal clothes
0:10:53 > 0:10:55'and everyone was downstairs.'
0:10:55 > 0:10:58- Grandpa!- Did I miss anything?
0:10:58 > 0:11:01Yes! Granddad Gilbert's been telling
0:11:01 > 0:11:04brilliant stories about Captain Dumbletwit.
0:11:04 > 0:11:06I did meet him! I did!
0:11:06 > 0:11:10He was right here. He flew the spaceship and everything!
0:11:10 > 0:11:14- Gilbert has a fantastic imagination. - How about we play?
0:11:14 > 0:11:17There's some wonderful old toys in here.
0:11:17 > 0:11:20Oh! I remember this old boat.
0:11:20 > 0:11:23We could sail this on the pond!
0:11:23 > 0:11:27I love playing with boats! Will you play with us, Grandpa?
0:11:27 > 0:11:30Em, maybe a bit later, Martha. I'm tired at the moment.
0:11:30 > 0:11:34Tired?! But, Grandpa, you haven't done anything!
