The Pit Beast is a monster who guards one of the lowest chambers of the Labyrinth, Trogg's base in the Land Beyond. Larger than the average fox and much more fierce, the Pit Beast is a purple, hairy fiend beset by nasty lesions all over its body. Despite relatively little room to move, it has been shown to have exercised regularly, sporting a small "ripped" stomach. However, its strength is severely handicapped by its low intelligence, being both slow to the draw and creating its own downfall.
The beast was used to guard Shirob when he was supposedly captured by Trogg. In reality, it was (unwittingly) part of Trogg's plan to lure Miles "Tails" Prower to the Zone. The monster initially appeared to want to eat Shirob, but was furious when Tails and Errol Blackthorn stole his dinner. It continuously persued the fleeing gang until Tails decided to fight it on his own. Ready to eat, the Pit Beast leapt at its target but bashed its large head on the rocky ceiling. The creature was visibly unhappy with its lot, crying whilst holding its head and yelling choruses of "Ow!". After its "defeat", the Pit Beast was not seen again.
