0:00:46 > 0:00:51I love running! I'm super fast and super jumpy.
0:00:51 > 0:00:53I'm the king of the castle!
0:00:53 > 0:00:56All hail King Messy!
0:00:56 > 0:00:58Phew! Oh, I'm out of breath
0:00:58 > 0:01:02after all that running and jumping. BABUM! BABUM! BABUM!
0:01:02 > 0:01:05And what's that babum-babum-babum noise?
0:01:05 > 0:01:07It sounds like my heart is playing the drums.
0:01:07 > 0:01:11I wonder why it makes that thumpy-bumpy noise.
0:01:11 > 0:01:15When you need to know, go to Okido!
0:01:20 > 0:01:23BOING!
0:01:23 > 0:01:26- Whoo!- Whoo! Careful, Messy!
0:01:26 > 0:01:28Hi, Felix! Hi, Zoe!
0:01:28 > 0:01:29Hi, Messy.
0:01:30 > 0:01:32And star jumps.
0:01:32 > 0:01:35Boing, boing, boing!
0:01:35 > 0:01:37And bottom bounce.
0:01:37 > 0:01:40LAUGHTER
0:01:40 > 0:01:42That was boing-tastic!
0:01:42 > 0:01:44And my heart's boinging again as well.
0:01:44 > 0:01:47- BABUM! BABUM! - Mine too!
0:01:47 > 0:01:49And mine!
0:01:49 > 0:01:51Why does it boing like that sometimes
0:01:51 > 0:01:54and other times you never hear it at all?
0:01:54 > 0:01:56Zim and Zam would know.
0:01:56 > 0:01:58HE WHISTLES
0:02:03 > 0:02:05Let's skidoodle, Okidoodle.
0:02:12 > 0:02:14Faster, Zim, faster!
0:02:14 > 0:02:17The cake mix needs to be whisked fast.
0:02:19 > 0:02:21- Hello!- Whaaa!
0:02:22 > 0:02:25BOTH: Hi, Zim. Hi, Zam.
0:02:25 > 0:02:28- BEEP! BEEP! - Oh, Messy, you gave me such a shock.
0:02:28 > 0:02:30I can hear my heart beating.
0:02:30 > 0:02:32That's why we've come!
0:02:32 > 0:02:36Yes, we want to know why our hearts make thumpy-bumpy, babum-babum
0:02:36 > 0:02:38boingy noises.
0:02:38 > 0:02:40If you please, Zoom.
0:02:40 > 0:02:43Your heart is really a muscle.
0:02:43 > 0:02:48But a special muscle because of what it does.
0:02:48 > 0:02:52It works like a pump sending blood around your body.
0:02:52 > 0:02:54The blood provides your body with the oxygen
0:02:54 > 0:02:56and nutrients it needs.
0:02:56 > 0:03:00Which helps keep it strong and healthy.
0:03:00 > 0:03:02HOWLING
0:03:02 > 0:03:06What is that? It's coming from outside.
0:03:06 > 0:03:07Well, you go and look.
0:03:07 > 0:03:11We've got a cake to bake.
0:03:11 > 0:03:13HOWLING
0:03:13 > 0:03:15It's coming from those mountains.
0:03:15 > 0:03:17Let's go and see what it is.
0:03:17 > 0:03:20Eh, we'll just drive the cloud ship then, shall we?
0:03:20 > 0:03:24Yes, good, good. Careful, you're spilling it.
0:03:24 > 0:03:28Oh, red buttons, my old friends.
0:03:28 > 0:03:31I think I've got a pressing engagement.
0:03:34 > 0:03:36Here we go!
0:03:39 > 0:03:42Wow! Look at the size of these mountains!
0:03:42 > 0:03:45HOWLING
0:03:45 > 0:03:51Hmm, and that funny "mmm-eeeee" is getting louder and louder.
0:03:51 > 0:03:54Got to get higher, Messy.
0:03:54 > 0:03:57ALL: Whoa!
0:03:57 > 0:03:58HOWLING
0:04:03 > 0:04:06HOWLING
0:04:06 > 0:04:09It's coming from that cave!
0:04:09 > 0:04:12Let's take a closer look.
0:04:12 > 0:04:14I think I know what makes that noise.
0:04:14 > 0:04:17You don't think Messy's flown us to the
0:04:17 > 0:04:19Land of the Mountain Giants, do you?
0:04:21 > 0:04:23What are those weird rocks?
0:04:23 > 0:04:26They're not rocks...
0:04:26 > 0:04:27they're teeth.
0:04:27 > 0:04:31And that's not a cave, it's a mouth!
0:04:31 > 0:04:34HOWLING
0:04:35 > 0:04:37ALL: Whoa!
0:04:39 > 0:04:43- Lofty's swallowed us!- BOTH: Whoa!
0:04:45 > 0:04:47Cool!
0:04:48 > 0:04:50We're in Lofty's bloodstream.
0:04:50 > 0:04:54But don't worry, the blood circulates all round the body.
0:04:54 > 0:04:57All we have to do is sit tight and wait
0:04:57 > 0:05:01until we get back to the top, so we can get out again.
0:05:04 > 0:05:07Yeah, but we're starting to slow down.
0:05:07 > 0:05:11Yes, the blood isn't moving as fast as it was.
0:05:11 > 0:05:12I wonder why.
0:05:12 > 0:05:14YAWNING
0:05:16 > 0:05:19Oh, dear. That sounded like a yawn.
0:05:19 > 0:05:21And if he goes to sleep... Zoom.
0:05:21 > 0:05:24You see, our heart beats faster or slower,
0:05:24 > 0:05:29depending on what we're doing. When we exercise it beats faster.
0:05:29 > 0:05:32This is because your body needs more energy
0:05:32 > 0:05:34and when it needs more energy,
0:05:34 > 0:05:37it needs more oxygen-filled blood.
0:05:37 > 0:05:41So your heart pumps faster to supply the oxygen-filled blood
0:05:41 > 0:05:43that your body needs.
0:05:43 > 0:05:46And when your body slows down...
0:05:46 > 0:05:48So does your heart.
0:05:48 > 0:05:50SNORING
0:05:54 > 0:05:56Oh, no! Lofty's asleep.
0:05:56 > 0:05:59That's why we're hardly moving!
0:05:59 > 0:06:02And we can't use the cloud ship engines in here
0:06:02 > 0:06:05because that might hurt Lofty.
0:06:05 > 0:06:08We need to get his heart pumping fast again.
0:06:08 > 0:06:11But how can we get out to wake him up?
0:06:11 > 0:06:13I've got just the thing.
0:06:13 > 0:06:17- Ta-da! The escape pod.- ALL: Hooray!
0:06:17 > 0:06:20It's only got three seats though.
0:06:20 > 0:06:23Yes... Which three of us should go?
0:06:23 > 0:06:25I think it should be me and...
0:06:25 > 0:06:28I know, but everyone else stays...
0:06:29 > 0:06:32Bye! See you!
0:06:32 > 0:06:37- Those three, then.- I suppose we could check on the cake.- Good idea.
0:06:38 > 0:06:42SNORING
0:06:42 > 0:06:45We've got to time this right or we'll be squashed.
0:06:45 > 0:06:48- I can't look.- Me neither.- Nor me.
0:06:49 > 0:06:54ALL: Aggggrrhhh!
0:06:56 > 0:06:59Wake up!
0:06:59 > 0:07:01Mr Giant!
0:07:01 > 0:07:03Lofty! Wake up!
0:07:03 > 0:07:04HE GRUMBLES
0:07:04 > 0:07:08We've got to get you and your blood moving.
0:07:08 > 0:07:11HE GRUMBLES
0:07:12 > 0:07:13Watch the cake.
0:07:13 > 0:07:17Oh, I think they've woken Lofty!
0:07:21 > 0:07:23Get away!
0:07:23 > 0:07:26Oh, yes! It's working, he's waking up.
0:07:26 > 0:07:30- But, Messy, look out! - Yeah, look out.
0:07:30 > 0:07:36- Wow! That made my heart thump. - Phew, me too.
0:07:36 > 0:07:39Have you come to my birthday party?
0:07:39 > 0:07:42Er, no, sorry.
0:07:42 > 0:07:44HE HOWLS
0:07:44 > 0:07:47Why do you keep making that noise, Lofty?
0:07:47 > 0:07:51I always make that sound when I'm sad.
0:07:52 > 0:07:54HE HOWLS
0:07:54 > 0:07:57Oh, but why are you sad?
0:07:57 > 0:08:00HE HOWLS
0:08:00 > 0:08:05Because no-one's come to my birthday party.
0:08:05 > 0:08:07Who did you invite?
0:08:07 > 0:08:13All the guys, all the giant guys but they haven't come.
0:08:13 > 0:08:17I wrote invitations to all of them as well, look.
0:08:18 > 0:08:24Er, Lofty, shouldn't you have given those invitations to your friends?
0:08:25 > 0:08:32Oh, dear! I feel like a giant fool.
0:08:32 > 0:08:35Well, you've still got time to deliver them.
0:08:35 > 0:08:38But, Messy, we've got to get Lofty's heart pumping fast.
0:08:38 > 0:08:42We've got to get him running around so we can get the cloud ship out.
0:08:42 > 0:08:48Hmm, I think I know how to do that and give Lofty his birthday party.
0:08:48 > 0:08:53Come on. Quick, Mr Giant, let's deliver these really, really fast.
0:08:56 > 0:08:58Here you go, one for you.
0:08:58 > 0:09:03One for you. Ha-ha, there you are.
0:09:03 > 0:09:05Brilliant idea, Messy.
0:09:05 > 0:09:11All this running must be getting Lofty's heart really pumping.
0:09:11 > 0:09:13We're definitely moving again.
0:09:13 > 0:09:16Agggrrrh!
0:09:17 > 0:09:22Right, that's all the invitations delivered and now I...
0:09:24 > 0:09:27HE GROANS
0:09:27 > 0:09:30HE SNEEZES
0:09:31 > 0:09:34Aggrrhh!
0:09:34 > 0:09:36Well done, Messy!
0:09:38 > 0:09:40BOTH: Happy Birthday.
0:09:40 > 0:09:43This is the best birthday ever!
0:09:44 > 0:09:47And I've got new friends at my party too.
0:09:47 > 0:09:52And after all that, we still managed to make our cake.
0:09:52 > 0:09:55- Let's eat it. - I can't wait to try it.
0:09:55 > 0:09:59Oh, you got me a birthday cake!
0:09:59 > 0:10:02No, no, wait, wait...!
0:10:02 > 0:10:06- Thank you! - We made it for our tea actually...
0:10:06 > 0:10:10Yummy! Oh, that's delicious.
0:10:10 > 0:10:13- Happy birthday. - Hope you've enjoyed it.
0:10:13 > 0:10:15I've had a great day too
0:10:15 > 0:10:18and now I know why my heart makes that drumming noise.
0:10:18 > 0:10:21Bye, everyone, and happy birthday, Lofty.
0:10:21 > 0:10:25- ALL: Bye, Messy.- Bye! See you, bye!
0:10:25 > 0:10:27My heart makes that thumpy-bumpy noise
0:10:27 > 0:10:31because it's pumping blood around my body.
0:10:31 > 0:10:33The more you do, the faster it beats.
0:10:33 > 0:10:35HE PANTS
