Invader Zim Episode 16 - A Room with a Moose Episode Title:A Room with a Moose.Episode Description:After reminiscing about his mistreatment at the hands of his schoolmates, Zim orchestrates a fake field trip, intending to launch the rest of his class into a wormhole in a spaceship disguised as a school bus. The wormhole leads to an alternate dimension which consists entirely of a room occupied by a moose. How the moose is meant to menace the children is not made explicitly clear, however Zim implies that upon arriving in the alternate dimension, the school bus will materialize inside the moose's mouth, to be eaten whole. After an internal struggle, Dib thwarts Zim's plan by weighing down the right side of the bus, causing it to veer onto an alternate path through the wormhole, which leads safely home.
