0:00:45 > 0:00:47- The Octonots, - and the Large Seaweed Forest.
0:01:00 > 0:01:02- Is my favourite sub - ready to go, Ira?
0:01:03 > 0:01:05- Yes, I've fitted an eject button.
0:01:05 > 0:01:09- It'll help you escape from the sub - in an emergency.
0:01:10 > 0:01:11- Yaw!
0:01:11 > 0:01:12- Yaw!- - Press this...
0:01:13 > 0:01:17- ..and you'll fly out before - you can say crunch your carrots.
0:01:20 > 0:01:23- Thanks, Ira. It's time for me - to test the new button.
0:01:23 > 0:01:24- Yaw!
0:01:25 > 0:01:27- Wait. I haven't told you - how to use it.
0:01:27 > 0:01:30- I press the button and I shoot out.
0:01:30 > 0:01:31- Easy.
0:01:31 > 0:01:35- First switch off the engine. - Then press the button.
0:01:36 > 0:01:39- Yes, OK. Open the Octohatch.
0:01:39 > 0:01:44- If you don't switch off the engine, - the sub will leave without you.
0:01:44 > 0:01:47- OK, off I go.
0:01:52 > 0:01:54- Whoo-hoo!
0:01:55 > 0:01:57- Whoo-hoo!
0:02:01 > 0:02:04- Let's test the eject button.
0:02:05 > 0:02:07- Um...?
0:02:08 > 0:02:09- Yahoo!
0:02:11 > 0:02:12- Huh?
0:02:13 > 0:02:17- My sub! - I forgot to switch off the engine.
0:02:19 > 0:02:21- D'oh!
0:02:36 > 0:02:40- Um... I had some problems.
0:02:40 > 0:02:42- You forgot, didn't you?
0:02:42 > 0:02:44- Forgot? No.
0:02:45 > 0:02:47- Forgot what?
0:02:48 > 0:02:50- Oh, OK.
0:02:50 > 0:02:55- I forgot to switch off the engine - before pressing the eject button.
0:02:55 > 0:02:58- There's no time to lose. - Let's find the sub.
0:02:59 > 0:03:01- Ira, sound the Octoalert.
0:03:04 > 0:03:06- Octonots, to the headquarters.
0:03:16 > 0:03:19- Octonots, there's a sub missing.
0:03:19 > 0:03:22- And I lost it.
0:03:22 > 0:03:27- The first thing to do is to look - for it. Dela, check the monitor.
0:03:27 > 0:03:30- That will show us - where Harri's sub is.
0:03:30 > 0:03:32- Right away, Captain.
0:03:41 > 0:03:42- There it is.
0:03:42 > 0:03:46- It looks to be stuck - in the middle of something.
0:03:46 > 0:03:50- Cregynnog, we need you - to tell us what it is.
0:03:50 > 0:03:53- Ira, we need - another sub immediately.
0:03:54 > 0:03:55- To the Octohatch.
0:04:00 > 0:04:01- Almost ready, Cap.
0:04:04 > 0:04:07- I can't wait to see - my favourite sub again.
0:04:08 > 0:04:11- Here are photos of you in Sub-2.
0:04:17 > 0:04:20- I painted those shark teeth myself.
0:04:21 > 0:04:26- We've won races together and - we've escaped from dangerous places.
0:04:27 > 0:04:31- No other sub is like it.
0:04:31 > 0:04:33- Don't worry. We'll get it back.
0:04:34 > 0:04:37- This shouldn't take long. - Is this sub ready?
0:04:39 > 0:04:40- Ready, Cap.
0:04:41 > 0:04:43- Yaw!
0:04:45 > 0:04:47- Ira, open the Octohatch.
0:04:47 > 0:04:48- Right away.
0:05:00 > 0:05:04- Captain, it looks as if - my favourite sub is nearby.
0:05:04 > 0:05:07- It should be easy to tow it home.
0:05:07 > 0:05:09- Yes, no bother at all.
0:05:14 > 0:05:15- Huh!
0:05:15 > 0:05:17- Huh!- - Look at that!
0:05:17 > 0:05:18- Surprising seas!
0:05:21 > 0:05:23- A seaweed forest.
0:05:26 > 0:05:31- The monitor's showing that - Harri's sub is inside the seaweed.
0:05:31 > 0:05:34- We'll have to go in to investigate.
0:05:34 > 0:05:36- Harri, take...
0:05:36 > 0:05:38- Harri!
0:05:39 > 0:05:41- Come on, Cregynnog.
0:05:50 > 0:05:52- Incredible.
0:05:52 > 0:05:55- This is the tallest seaweed - in the sea.
0:05:55 > 0:06:00- It stretches up and up to allow - the leaves to reach the sunshine.
0:06:01 > 0:06:06- Just like land forests, the seaweed - trees are home to many creatures.
0:06:06 > 0:06:11- It won't be easy finding the sub - in such a large seaweed forest...
0:06:11 > 0:06:13- ..but we're close.
0:06:14 > 0:06:16- This way.
0:06:20 > 0:06:21- Whoa.
0:06:21 > 0:06:25- Careful. There's a huge orange - shark in the forest.
0:06:25 > 0:06:29- An orange shark? - Hold on, it must be the sub.
0:06:29 > 0:06:30- Come back!
0:06:33 > 0:06:36- What did you say - about an orange shark?
0:06:36 > 0:06:38- I saw it in the forest.
0:06:38 > 0:06:41- This is my hiding place - so away you go.
0:06:42 > 0:06:44- Is this what you saw?
0:06:44 > 0:06:46- Is this what you saw?- - Yes. I can't look at it.
0:06:46 > 0:06:47- It scares me so much.
0:06:48 > 0:06:50- They're not real teeth.
0:06:50 > 0:06:52- I painted them - look.
0:06:53 > 0:06:54- Stay back.
0:06:54 > 0:06:57- Harri, you'd better - step back because...
0:06:57 > 0:06:59- Because of what?
0:07:02 > 0:07:04- When a shark's threatened...
0:07:04 > 0:07:09- ..it takes in enough water to - swell up like a balloon and then...
0:07:09 > 0:07:11- Yes, I know what happens next.
0:07:12 > 0:07:15- Look. We're even closer to the sub.
0:07:16 > 0:07:18- I'm coming to rescue you, sub!
0:07:23 > 0:07:25- Hey, what's happening, lads?
0:07:26 > 0:07:28- A shovel-nosed guitar fish.
0:07:28 > 0:07:30- Oh, no, does this one spit, too?
0:07:30 > 0:07:33- No, he hides under the sand.
0:07:33 > 0:07:34- I knew.
0:07:35 > 0:07:37- We're looking for a sub.
0:07:37 > 0:07:42- It's Sub-2 and it's bright orange. - Have you seen it?
0:07:42 > 0:07:47- It should be somewhere around here - but we can't see it.
0:07:48 > 0:07:51- I don't know about that.
0:07:51 > 0:07:55- When you feel strange, - you should look up.
0:07:58 > 0:08:01- All these creatures - are no help at all.
0:08:01 > 0:08:03- We'll never find it.
0:08:04 > 0:08:06- It's worth looking up.
0:08:06 > 0:08:08- Wait, let's look up.
0:08:08 > 0:08:13- Captain, a seaweed is like - a tall building with many floors.
0:08:15 > 0:08:19- So far, we've only looked - for the sub down here.
0:08:19 > 0:08:22- It could be up there somewhere.
0:08:25 > 0:08:27- Octonots, away we go.
0:08:40 > 0:08:44- The monitor says - the sub should be here.
0:08:48 > 0:08:49- Why can't we see it?
0:08:50 > 0:08:52- Where can it be?
0:08:52 > 0:08:54- Psst, you! Yes, you.
0:08:54 > 0:08:57- Ha, ha, ha. Here, over here.
0:08:57 > 0:08:59- Who said that?
0:08:59 > 0:09:00- Who said that?- - Up here.
0:09:00 > 0:09:02- Up where?
0:09:02 > 0:09:04- Here!
0:09:04 > 0:09:05- Where?
0:09:06 > 0:09:09- Here. Here.
0:09:14 > 0:09:17- Captain, the seaweed leaves - are talking to me!
0:09:17 > 0:09:19- The seaweed leaves?
0:09:19 > 0:09:20- The seaweed leaves?- - Talking?
0:09:20 > 0:09:22- They say my sub is here.
0:09:24 > 0:09:25- But where?
0:09:25 > 0:09:29- There's nothing here but seaweed.
0:09:29 > 0:09:30- CLANK
0:09:36 > 0:09:38- Not... Not...
0:09:41 > 0:09:44- My sub! Yeah!
0:09:44 > 0:09:48- Did you miss me? I missed you, too.
0:09:48 > 0:09:51- We told you - it was right in front of you.
0:09:51 > 0:09:53- You're not talking seaweed.
0:09:53 > 0:09:56- I'm a seaweed fish. - That's what we all are.
0:10:01 > 0:10:03- They look like seaweed leaves.
0:10:03 > 0:10:07- Which makes it easy for us - to hide wherever we are.
0:10:08 > 0:10:11- Come on, children, - play time is over.
0:10:12 > 0:10:14- Hey, Mam, we fooled them.
0:10:14 > 0:10:17- They thought we were leaves.
0:10:19 > 0:10:21- Really, children?
0:10:22 > 0:10:26- Octonots, let's remove Harri's sub - from the forest.
0:10:26 > 0:10:29- Yaw! Right away, Captain.
0:10:32 > 0:10:35- It's nice to be back - in my favourite sub.
0:10:35 > 0:10:39- Put your feet up, Harri, - but not on the eject button!
0:10:39 > 0:10:41- Very funny!
0:10:41 > 0:10:42- Yaw!
0:10:43 > 0:10:44- Oh, Harri
0:10:58 > 0:10:58- .
