0:00:02 > 0:00:0530 seconds to air, everyone! All set, Dr Knowles?
0:00:05 > 0:00:08Well, I am, Colin, but someone's too busy
0:00:08 > 0:00:09playing with their silly new invention.
0:00:09 > 0:00:13Excuse me, my state-of-the-art super-shrinker is not silly.
0:00:13 > 0:00:15It's genius!
0:00:15 > 0:00:17MCCORK LAUGHS
0:00:18 > 0:00:20Oh, hang on, I think it's jammed.
0:00:20 > 0:00:22Let me take a look here...
0:00:23 > 0:00:24Whoa! Aargh!
0:00:25 > 0:00:27BELL RINGS
0:00:27 > 0:00:28Positions, everybody!
0:00:28 > 0:00:32This is Brain Freeze!
0:00:32 > 0:00:34With...
0:00:42 > 0:00:44Stand by...
0:00:44 > 0:00:46Come on, everybody!
0:00:48 > 0:00:49Wahey!
0:00:49 > 0:00:51- BOTH:- It's showtime!
0:00:54 > 0:00:55Today, we're asking...
0:00:58 > 0:01:00What the...
0:01:00 > 0:01:03Millions of years ago, the earth was ruled by dinosaurs
0:01:03 > 0:01:07and to this day, they are still the largest land animals ever to exist.
0:01:07 > 0:01:09T-Rex, was he the biggest?
0:01:09 > 0:01:11Actually, no.
0:01:11 > 0:01:13The largest dinosaurs were herbivores,
0:01:13 > 0:01:16meaning that they only ate plants.
0:01:16 > 0:01:18These huge sauropods are thought to have measured
0:01:18 > 0:01:23up to 35 metres in length and weighed the same as 18 elephants!
0:01:23 > 0:01:27But to find out what animal is even bigger than the dinosaurs,
0:01:27 > 0:01:31- join us after this break... - Careful, Professor!
0:01:33 > 0:01:38McCork...McCork... Oh, there you are, McCork.
0:01:38 > 0:01:41Aargh! There's two giants on the loose! Help!
0:01:41 > 0:01:43Right, I've almost fixed this thing.
0:01:43 > 0:01:46If I could just reverse the magnification...
0:01:46 > 0:01:50Oh, Jonathan, look at the adorable little dolly!
0:01:50 > 0:01:53Ah, put me down. I'm not a doll!
0:01:53 > 0:01:56Your little arms and your little face! You're so cute...
0:01:56 > 0:02:00Oh, no! What are we going to do, Colin? The show's about to start!
0:02:00 > 0:02:03Don't you worry, Dr Knowles...
0:02:06 > 0:02:07Huh?!
0:02:07 > 0:02:10We're live in five...four...three...
0:02:16 > 0:02:20- So, tell us, Dr Knowles... - Ahem, camera two, Colin.
0:02:20 > 0:02:25So, tell us, Dr Knowles, what is the largest animal of all time?
0:02:25 > 0:02:29Measuring up to 30 metres and weighing up to 180 tonnes,
0:02:29 > 0:02:32the blue whale is the largest animal on earth.
0:02:32 > 0:02:35Everything about this animal is huge.
0:02:35 > 0:02:37Its heart is the size of a small car,
0:02:37 > 0:02:42and its tongue alone is so big, 50 people could stand on it!
0:02:44 > 0:02:47Gosh! Now, that's big!
0:02:47 > 0:02:49Blue whales are still on the endangered list,
0:02:49 > 0:02:52but their numbers are slowly recovering.
0:02:52 > 0:02:55And it's our job as scientists to help ensure a future
0:02:55 > 0:02:58for this gentle giant of the ocean.
0:02:58 > 0:02:59- Boo!- Aargh!
0:02:59 > 0:03:03What do you mean "scientists"? You're only the floor manager.
0:03:03 > 0:03:06Oh, McCork, get off my head! Even when you're tiny, you're trouble.
0:03:06 > 0:03:09- Get off me! - See you next time...I hope.
0:03:12 > 0:03:14Let me go! Let me go!
0:03:14 > 0:03:17Well, McCork, that's enough of your tiny mischief.
0:03:17 > 0:03:21Reverse the super-shrinker!
0:03:21 > 0:03:23DR KNOWLES COUGHS
0:03:23 > 0:03:27Oh, dear! I think I might have overdone the calculations.
0:03:27 > 0:03:32Jonathan, have you seen my dolly? I can't find her anywhere.
0:03:32 > 0:03:37How's it going, Ms Hucklebaby? Ha-ha-ha!
0:03:37 > 0:03:41Oh, look at the cute little dollies! Oh, they're so cutsie-wootsie!
0:03:41 > 0:03:44Put me down! Put me down!
0:03:44 > 0:03:49- Ha-ha-ha!- Oh, stop it! Stop it, McCork, that tickles!
