Scrat the sabre-toothed squirrel is climbing it to find his acorn. He has some difficulties climbing it like getting his tongue stuck and nearly falling off but he manages to hold on to the edge by digging his claws and sabre teeth into the ice. He saw his acorn which is wedged into the ice, much to his delight. He runs up to it and smiles. He then tries to pull it out of the ice though it is hard to begin with but eventually manages to pull it free and hugs it. But then, there is a rumbling noise and a piece of ice comes loose, releasing a jet of water. He quickly uses a claw to plug it up, stopping the water. But another piece of ice comes loose and another jet of water comes out, forcing Scrat to put his acorn in his mouth and plug it up with another claw. But another water jet comes out and Scrat has to use it back right-hand paw to plug it up and catches his acorn in his back left-hand paw and has to use that to plug another jet of water up, which forces Scrat to balance his acorn on his head. The rumble sound is heard again and a jet of water hits Scrat in the eye until he uses his mouth to contain it. Then the water inside Scrat's mouth causes him to inflate with water and his claws are removed from the other jets of water, releasing them. And no, he will never explode, just grows bigger.
