Mutabor!!!

A small, white, bird-like creature with a long beak and limbs emerges from a dark, shadowy hole in a stone staircase, then runs across a dimly lit, red-hued cavern. The creature is pursued by a group of larger, grotesque, white creatures with bird-like heads and multiple limbs, who chase it through the cavern, climb a rope, and eventually fall into a pit, while the small creature escapes across a wooden bridge.
