SOURCE: At the Earth's Core by Edgar Rice Burroughs (All-Story Weekly, April 4-25, 1914)

DESCRIPTION: "Presently a door in one side of the arena wall was opened to admit a huge, shaggy, bull-like creature....As the animal approached the two, bellowing and pawing the ground with the strength of many earthly bulls, another door directly beneath us was opened, and from it issued the most terrific roar that ever had fallen upon my outraged ears..." (At the Earth's Core by Edgar Rice Burroughs)

NOTES: The Bos or Thag is a dangerous, short-tempered creature.

HISTORY: This is the scene that George Lucas pays homage to in the arena scene in Attack of the Clones.
