The Beasts are creatures that appear in the Goosebumps book, The Beast from the East.
The Beasts are 8 ft. bear-faced creatures with blue fur, a long-snout, a primate-like body, and a beaver-like tail. They live in a strange forest and spend their time playing a deadly game of tag, in which the loser is eaten. It is also apparent that the better a Beast is at playing the game, the more abilities they are able to perform. Beasts are honor bound by the rules of the game.
A Beast appears as an enemy, you have to get passed him to dig out the security card, to do that, use The Shrunken Head, it will overpower him.
