0:00:56 > 0:01:01- Phew! Oh, I'm out of breath - after all that running and jumping.
0:01:01 > 0:01:04- And what's - that babum-babum-babum noise?
0:01:04 > 0:01:08- It sounds like my heart - is playing the drums.
0:01:08 > 0:01:11- I wonder why it makes - that thumpy-bumpy noise?
0:01:12 > 0:01:14- When you need to know, go to Ocido!
0:01:22 > 0:01:24- Whoo!
0:01:25 > 0:01:26- Careful, Blero.
0:01:27 > 0:01:28- Hi, Dylan! Hi, Sian!
0:01:28 > 0:01:29- Hi, Dylan! Hi, Sian!- - Hi, Blero.
0:01:30 > 0:01:32- And star jumps.
0:01:32 > 0:01:35- Boing, boing, boing!
0:01:35 > 0:01:37- And bottom bounce.
0:01:38 > 0:01:41- That was boing-tastic!
0:01:42 > 0:01:44- My heart's boinging again as well.
0:01:45 > 0:01:47- Mine too.
0:01:47 > 0:01:48- Mine too.- - And mine.
0:01:49 > 0:01:51- Why does it boing - like that sometimes...
0:01:51 > 0:01:53- ..and other times - you never hear it at all?
0:01:54 > 0:01:56- Sim and Sam would know.
0:02:01 > 0:02:04- Let's skidoodle, Ocidoodle.
0:02:12 > 0:02:14- Faster, Sim, faster!
0:02:14 > 0:02:18- The cake mix - needs to be whisked fast.
0:02:18 > 0:02:20- Hello!
0:02:22 > 0:02:24- Hi, Sim. Hi, Sam.
0:02:25 > 0:02:27- Oh, Blero, you gave me such a shock.
0:02:28 > 0:02:30- I can hear my heart beating.
0:02:30 > 0:02:32- That's why we've come!
0:02:32 > 0:02:34- We want to know - why our hearts make...
0:02:34 > 0:02:37- ..thumpy-bumpy, - babum-babum boingy noises.
0:02:38 > 0:02:40- If you please, Swn.
0:02:40 > 0:02:43- Your heart is really a muscle.
0:02:43 > 0:02:47- But a special muscle - because of what it does.
0:02:47 > 0:02:51- It works like a pump - sending blood around your body.
0:02:51 > 0:02:56- The blood provides your body with - the oxygen and nutrients it needs.
0:02:56 > 0:03:00- Which helps keep it strong - and healthy.
0:03:00 > 0:03:01- HOWLING
0:03:02 > 0:03:05- What is that? - It's coming from outside.
0:03:06 > 0:03:09- Well, you go and look. - We've got a cake to bake.
0:03:09 > 0:03:10- HOWLING
0:03:11 > 0:03:14- It's coming from those mountains.
0:03:14 > 0:03:16- Let's go and see what it is.
0:03:17 > 0:03:19- We'll just drive - the cloud ship then, shall we?
0:03:20 > 0:03:23- Yes, good, good. - Careful, you're spilling it.
0:03:24 > 0:03:27- Oh, red buttons, my old friends.
0:03:28 > 0:03:30- I think I've got - a pressing engagement.
0:03:33 > 0:03:35- Here we go.
0:03:39 > 0:03:42- Wow! - Look at the size of these mountains.
0:03:43 > 0:03:44- HOWLING
0:03:46 > 0:03:51- That funny mmm-eeeee - is getting louder and louder.
0:03:51 > 0:03:53- Got to get higher, Blero.
0:03:53 > 0:03:55- Whoa!
0:03:56 > 0:03:58- HOWLING
0:04:05 > 0:04:06- HOWLING
0:04:06 > 0:04:08- It's coming from that cave!
0:04:09 > 0:04:10- Let's take a closer look.
0:04:11 > 0:04:13- I think I know - what makes that noise.
0:04:13 > 0:04:16- You don't think Blero's flown us...
0:04:16 > 0:04:18- ..to the Land of the Mountain - Giants, do you?
0:04:21 > 0:04:23- What are those weird rocks?
0:04:23 > 0:04:27- They're not rocks... they're teeth.
0:04:27 > 0:04:30- And that's not a cave, it's a mouth!
0:04:32 > 0:04:33- HOWLING
0:04:34 > 0:04:36- Whoa!
0:04:40 > 0:04:42- Talfryn's swallowed us!
0:04:45 > 0:04:47- Cool!
0:04:48 > 0:04:50- We're in Talfryn's bloodstream.
0:04:50 > 0:04:54- But don't worry, the blood - circulates all round the body.
0:04:54 > 0:04:59- All we have to do is sit tight and - wait until we get back to the top...
0:04:59 > 0:05:01- ..so we can get out again.
0:05:04 > 0:05:06- Yeah, - but we're starting to slow down.
0:05:07 > 0:05:10- Yes, the blood isn't moving - as fast as it was.
0:05:11 > 0:05:12- I wonder why?
0:05:12 > 0:05:14- YAWNING
0:05:15 > 0:05:18- Oh, dear. That sounded like a yawn.
0:05:18 > 0:05:21- And if he goes to sleep... Swn?
0:05:21 > 0:05:26- Our heart beats faster or slower, - depending on what we're doing.
0:05:26 > 0:05:29- When we exercise it beats faster.
0:05:29 > 0:05:32- This is because your body - needs more energy...
0:05:32 > 0:05:36- ..and when it needs more energy, - it needs more oxygen-filled blood.
0:05:37 > 0:05:40- Your heart pumps faster - to supply the oxygen-filled blood...
0:05:41 > 0:05:43- ..that your body needs.
0:05:43 > 0:05:46- And when your body slows down...
0:05:46 > 0:05:48- So does your heart.
0:05:48 > 0:05:49- SNORING
0:05:54 > 0:05:56- Oh, no! Talfryn's asleep.
0:05:56 > 0:05:59- That's why we're hardly moving.
0:05:59 > 0:06:02- We can't use the cloud ship - engines in here...
0:06:02 > 0:06:05- ..because that might hurt Talfryn.
0:06:05 > 0:06:08- We need to get - his heart pumping again.
0:06:08 > 0:06:10- How can we get out to wake him up?
0:06:10 > 0:06:12- How can we get out to wake him up?- - I've got just the thing.
0:06:13 > 0:06:15- Ta-da! The escape pod.
0:06:16 > 0:06:17- Hooray!
0:06:17 > 0:06:20- It's only got three seats though.
0:06:20 > 0:06:23- Yes... Which three of us should go?
0:06:23 > 0:06:25- I think it should be me and...
0:06:25 > 0:06:27- I know, but...
0:06:29 > 0:06:30- See you!
0:06:32 > 0:06:33- Those three then.
0:06:33 > 0:06:35- I suppose we could check - on the cake.
0:06:39 > 0:06:41- SNORING
0:06:42 > 0:06:45- We've got to time this right - or we'll be squashed.
0:06:45 > 0:06:46- I can't look.
0:06:46 > 0:06:48- I can't look.- - Me neither.
0:06:48 > 0:06:50- Argh!
0:06:57 > 0:06:58- Wake up.
0:06:58 > 0:07:00- Wake up.- - Mr Giant!
0:07:00 > 0:07:02- Talfryn! Wake up!
0:07:02 > 0:07:03- HE GRUMBLES
0:07:04 > 0:07:07- We've got to get you - and your blood moving.
0:07:07 > 0:07:09- Leave me alone.
0:07:12 > 0:07:14- Watch the cake.
0:07:14 > 0:07:16- Oh, I think they've woken Talfryn.
0:07:21 > 0:07:23- Get away!
0:07:23 > 0:07:25- It's working, he's waking up.
0:07:25 > 0:07:27- But Blero, look out!
0:07:30 > 0:07:33- Wow! That made my heart thump.
0:07:33 > 0:07:34- Phew, me too.
0:07:35 > 0:07:39- Have you come to my birthday party?
0:07:39 > 0:07:41- Er, no.
0:07:41 > 0:07:43- HE HOWLS
0:07:44 > 0:07:46- Why do you keep making that noise.
0:07:48 > 0:07:51- I always make that sound - when I'm sad.
0:07:51 > 0:07:54- HE HOWLS
0:07:54 > 0:07:56- Oh, but why are you sad?
0:07:57 > 0:07:58- HE HOWLS
0:07:59 > 0:08:04- Because no-one's - come to my birthday party.
0:08:04 > 0:08:07- Who did you invite?
0:08:08 > 0:08:13- All the guys, all the giant guys - but they haven't come.
0:08:13 > 0:08:17- I wrote invitations - to all of them as well, look.
0:08:18 > 0:08:24- Shouldn't you have given - those invitations to your friends?
0:08:28 > 0:08:32- Oh, dear! I feel like a giant fool.
0:08:33 > 0:08:35- Well, you've still got time - to deliver them.
0:08:36 > 0:08:39- We've got to get Talfryn's heart - pumping fast.
0:08:39 > 0:08:43- We've got to get him running around - so we can get the cloud ship out.
0:08:43 > 0:08:47- I think I know how to do that and - give Talfryn his birthday party.
0:08:47 > 0:08:48- Come on.
0:08:49 > 0:08:53- Quick, Mr Giant, let's deliver - these really, really fast.
0:08:56 > 0:08:58- Here you go, one for you.
0:08:58 > 0:09:01- One for you. Ha-ha, there you are.
0:09:03 > 0:09:04- Brilliant idea, Blero.
0:09:05 > 0:09:10- All this running must be getting - Talfryn's heart really pumping.
0:09:10 > 0:09:13- We're definitely moving again.
0:09:13 > 0:09:15- Argh!
0:09:17 > 0:09:23- Right, that's all the invitations - delivered and now I...
0:09:23 > 0:09:24- HE GROANS

0:10:15 > 0:10:18- I know why my heart - makes that drumming noise.
0:10:18 > 0:10:21- Bye, everyone, - and happy birthday, Talfryn.
0:10:21 > 0:10:23- Bye, Blero.
0:10:25 > 0:10:27- My heart - makes that thumpy-bumpy noise...
0:10:28 > 0:10:31- ..because it's pumping blood - around my body.
0:10:31 > 0:10:33- The more you do, - the faster it beats.
