You were just enrolled in the Sixth Worldwide Sponsored Robot Tournament! As a competitor? As a spectator? That's for you to decide! You decide to visit the sixth tier: The Cryo Laboratory. A vast research laboratory located in a frozen tundra, it is filled with scientists and research robots studying ice and determining bizarre applications for it (such as ice that is not slippery). After getting to the end of the lab, you enter a room tp fight the tier boss.... who is actually frozen in a block of ice. After moving past him, you fall down in a cave, where you are greeted by a man who looks a lot like Adam Savage for some reason... Though he does seem to be the replacement for the tier boss Dr. Vicious: Welcome back to Fablebusters! Today, folks, we're testing a very special fable, with the help of our new guest! Today, we'll be testing if our guest can fight our state-of-the-art mecha that my co-host is piloting! Let's turn the lights on our masterpiece! The Ice Buster is shown, a giant walrus robot with features that make it resemble said co-host, Dr. Hyneman (via a beret, glasses, and a small mustache), with the doctor piloting said mecha Dr. Vicious: As you see here, we have the "Ice Buster" in its natural habitat! Or perhaps, a rare breed of Ice Buster. One where you cross a robot walrus with a Hyena.... man! Ha ha! Dr. Hyenaman: Were those cosmetic modifications of yours necessary, Vicious? Dr. Vicious: Hey now, we need someone to smile for the camera! Dr. Hyenaman: Veeeeeey funny.
