0:00:01 > 0:00:04Not the shrinking cap, Grandpa.
0:00:06 > 0:00:08Catch me if you can!
0:00:08 > 0:00:11Grandpa!
0:00:17 > 0:00:20No! Be careful!
0:00:25 > 0:00:26Grandpa, stop!
0:00:35 > 0:00:37Ooh-oooh!
0:00:37 > 0:00:38CRASH!
0:00:48 > 0:00:52'The thing about Grandpa is that he's always fun.
0:00:52 > 0:00:54'We read stories.'

0:00:58 > 0:01:02'We play lots of games.'
0:01:02 > 0:01:05Whee!
0:01:05 > 0:01:09'One of the things I like doing best is making pictures.'
0:01:09 > 0:01:11Ha, ha!
0:01:11 > 0:01:14'We share our ice cream.
0:01:14 > 0:01:19'And today we were doing armchair exercises.
0:01:19 > 0:01:22'But we weren't the only ones getting exercise.
0:01:22 > 0:01:26'Dad and Jemima had gone on a massively long bike ride.
0:01:26 > 0:01:29'And mum's latest hobby was this...'
0:01:29 > 0:01:33# Shake those fingers to the left, to the right... #
0:01:33 > 0:01:39'Salsa dancing! In fact, everyone in Sunnysands had gone fitness mad.
0:01:39 > 0:01:41'We were all trying to...'
0:01:46 > 0:01:49Keep it up, Grandpa. It's really important you keep fit.
0:01:49 > 0:01:53It must be awful having to spend all your time in that chair.
0:01:53 > 0:01:58'Mum has no idea that when Grandpa puts his shrinking cap on,
0:01:58 > 0:02:00'he's more energetic than all of us!'
0:02:00 > 0:02:03Come to the bike shop with me, Jason, we'll be busy
0:02:03 > 0:02:06as it's Shake Up and Shape Up... Oh!
0:02:06 > 0:02:10'Mum had tripped over Jemima's dolls, Peter and Persephone.
0:02:10 > 0:02:12'Luckily she wasn't hurt.'
0:02:12 > 0:02:13Look, how cute is that?!
0:02:13 > 0:02:18Peter and Persephone are dressed for the Shake Up and Shape Up too.
0:02:18 > 0:02:19What a snazzy outfit.
0:02:19 > 0:02:23I could do with something like that to exercise in.
0:02:23 > 0:02:26Ha, ha! Grandpa, you are so funny!
0:02:26 > 0:02:30I'll just make up the lunch boxes and then we'll go, tuna mayo OK?
0:02:30 > 0:02:33'I knew what Grandpa was thinking.
0:02:33 > 0:02:35'And it was a very worrying thought.'
0:02:35 > 0:02:38Not the shrinking cap, Grandpa!
0:02:40 > 0:02:42Catch me if you can!
0:02:42 > 0:02:46'You know when Grandpa shrinks,
0:02:46 > 0:02:49'he can get up to all kinds of magical things.
0:02:49 > 0:02:52'He can get into my car and make it go...
0:02:54 > 0:02:57'He can fly off in my plane.
0:02:57 > 0:03:01'He can glide on Gordon, my toy seagull.'
0:03:01 > 0:03:03Grandpa!
0:03:03 > 0:03:07'Or he could just run for all he's worth.'
0:03:14 > 0:03:17Oh, has Grandpa gone for a lie down?
0:03:17 > 0:03:20All that exercising must have worn him out.
0:03:20 > 0:03:24We'll take the music to the shop and practise between customers.
0:03:24 > 0:03:27- But...- Come on, Jason Mason!
0:03:27 > 0:03:28Oh...

0:03:30 > 0:03:34'So mum and I went off to the bike shop in the camper.
0:03:34 > 0:03:35'And mum said,
0:03:35 > 0:03:39' "I could really do with a partner for my salsa dancing."
0:03:39 > 0:03:42'And I said, what about Dad?
0:03:42 > 0:03:46- 'And mum said,- "Ha, ha, Dad! He's got two left feet.
0:03:46 > 0:03:48' "He can't dance any better than Grandpa."
0:03:48 > 0:03:51'And I thought, "If only she knew!"
0:03:51 > 0:03:54'Soon we arrived at the bike shop.
0:03:54 > 0:03:58'It's called Lend It, Mend It and Vend It.
0:03:58 > 0:04:03'Because we lend, mend and sell bikes.
0:04:03 > 0:04:10'We'd been at the shop for a while but there was no sign of Grandpa.
0:04:10 > 0:04:13'I started to think he had stayed home after all.'
0:04:13 > 0:04:16SALSA MUSIC PLAYS
0:04:16 > 0:04:19Oh! Run out of bells.
0:04:19 > 0:04:24'All that chasing after Grandpa had made me feel hungry.
0:04:24 > 0:04:30'So, I opened my lunchbox and what should I find instead of my banana?'
0:04:31 > 0:04:33Grandpa!
0:04:35 > 0:04:41At last, I thought you'd never open up. It stinks of tuna in here!
0:04:41 > 0:04:43What are you doing?
0:04:43 > 0:04:47I've come to Shake Up and Shape Up of course!
0:04:50 > 0:04:54Not here, you can't. Somebody will see you.
0:04:54 > 0:04:59'But once Grandpa has an idea, there's no stopping him.
0:05:00 > 0:05:05'Grandpa was well away. Dancing the cha cha cha up and down the counter.
0:05:05 > 0:05:09'Then all of a sudden, the door opened and who walked in but...
0:05:09 > 0:05:11'Mr Whoops!'
0:05:11 > 0:05:12Whoops!
0:05:14 > 0:05:15This is a surprise.
0:05:15 > 0:05:19I thought I'd do my bit for Shake Up and Shape Up week.
0:05:19 > 0:05:22- So I've decided to buy a bike. - That's marvellous.
0:05:22 > 0:05:27I've got a perfect bike in the workshop for you. Come and see.
0:05:27 > 0:05:30Oh, how exciting! Whoops! What colour is it?
0:05:30 > 0:05:33Mr Whoops riding a bike?!
0:05:33 > 0:05:39We can't let that happen, Jason. It'll be a disaster.
0:05:39 > 0:05:42'I had to agree with Grandpa. You see,
0:05:42 > 0:05:49'Mr Whoops is called that because he's always having little accidents.
0:05:53 > 0:05:55- 'He drops things...'- Oh!
0:05:55 > 0:05:59- Oh!- 'He falls over things...'
0:05:59 > 0:06:00Whoops!
0:06:03 > 0:06:04'He falls off things...'
0:06:04 > 0:06:06Whoops.
0:06:06 > 0:06:11- 'He even trips over his own feet!' - Whoops!
0:06:12 > 0:06:17'We needed to stop Mr Whoops from buying a bike, we needed a plan.
0:06:17 > 0:06:19'But there was no time for a plan!
0:06:19 > 0:06:26'Just then, Mr Whoops and mum came back in wheeling a shiny red bike.'
0:06:26 > 0:06:27This so exciting!
0:06:27 > 0:06:30I've never even sat on a bike before.
0:06:30 > 0:06:33Now I'm going to ride one all over Sunnysands.
0:06:33 > 0:06:37It's very hard, Mr Whoops. Maybe you should try a different sport.
0:06:37 > 0:06:40- Do you think so? Like what?- Em...
0:06:40 > 0:06:43Like...cricket?
0:06:43 > 0:06:48Oh, no! I'm not very good with bats. Whoops!
0:06:49 > 0:06:51Em, maybe...
0:06:51 > 0:06:52Football?
0:06:52 > 0:06:55Oh, no, I'm not very good with balls.
0:06:55 > 0:06:58- Whooo-oops!- Ha, ha!
0:06:58 > 0:07:00Bike riding is definitely for me.
0:07:00 > 0:07:02I'm sure you'll be fine.
0:07:02 > 0:07:06- Let's try it out now.- Oh, yes, let's. Shall I put that leg...
0:07:06 > 0:07:08- You can...- 'So Mum held the bike,
0:07:08 > 0:07:11'while Mr Whoops climbed on.'
0:07:11 > 0:07:15I think I've got it. Yes...
0:07:15 > 0:07:18'He put his feet carefully on the pedals and...
0:07:18 > 0:07:19Whoooooops...
0:07:19 > 0:07:23- 'I quickly hid Grandpa so they couldn't see him.'- Oh!
0:07:23 > 0:07:26Perhaps the saddle is too high.
0:07:26 > 0:07:28Ah! This is what I need.
0:07:28 > 0:07:31HE GASPS
0:07:31 > 0:07:35Ooh! What's this? A little cyclist!
0:07:35 > 0:07:40- That's Jemima's doll, Peter. Did you bring it with you, Jason?- Sort of.
0:07:40 > 0:07:44He could be my lucky mascot. I love his outfit.
0:07:44 > 0:07:48Do you have anything like that in my size?
0:07:48 > 0:07:52'The good news was, mum did have a cycling suit to fit Mr Whoops.
0:07:52 > 0:07:57'The bad news was, Mr Whoops had put his lucky mascot on the handlebars.'
0:07:57 > 0:08:00Why don't you take the bike for a test ride?
0:08:00 > 0:08:04Yes. Now I've got my lucky mascot, I can do anything.
0:08:06 > 0:08:09'Everything was going wrong.
0:08:09 > 0:08:13'Grandpa's plan was to stop him riding a bike - not go with him!'
0:08:13 > 0:08:17Time to Shake Up and Shape Up! Here we go!
0:08:17 > 0:08:20- Oooh!- Good luck, keep pedalling!
0:08:20 > 0:08:25Don't look so worried, Jason, I'm sure Mr Whoops'll be fine.
0:08:25 > 0:08:29- I think he'll LOVE cycling! - CRASH!
0:08:29 > 0:08:33Whoops!
0:08:33 > 0:08:39'Mum put some bandages on Mr Whoops, I took his mascot off the bike,
0:08:39 > 0:08:41'and put him on the counter.
0:08:41 > 0:08:46'I was hoping Mr Whoops' accident had put him off bike riding,
0:08:46 > 0:08:48- 'but no...'- I nearly did it!
0:08:48 > 0:08:50I'm gonna try one more time.
0:08:50 > 0:08:52No, you mustn't, you can't!
0:08:52 > 0:08:56Of course he can. You know, "if at first you don't succeed..."
0:08:56 > 0:08:59Try doing something else!
0:09:01 > 0:09:05Everybody is good at something, you just have to find out what it is.
0:09:05 > 0:09:08But I'm not good at any sports.
0:09:08 > 0:09:13'Then I saw Grandpa. He was sending me a message.'
0:09:13 > 0:09:19It doesn't have to be a sport, Mr Whoops. How about salsa dancing?
0:09:19 > 0:09:23- Salsa dancing?- Perfect!
0:09:23 > 0:09:26- Come on, Mr Whoops.- Whoooops!

0:10:05 > 0:10:09How would you rather travel, in my pocket or my lunchbox?
