After reminiscing about his mistreatment from his schoolmates, Zim summons up a false field trip, (which GIR says is a place made entirely of food), intending to lauch the rest of his class into a wormhole in a spaceship disguised as a school bus. The wormhold leads to an alternate dimension which has a room occupied by a moose in which they’ll meet “their moosey fate”. How the moose is meant to menace the schoolmates is not made entierley clear. However, Zim implies that once the school bus arrives in the dimension, the bus will be eaten whole by the moose. After an internal struggle, Dib thwarts Zim’s plan by weighing down the right side of the bus to veer into a path in the wormhole, which leads back to Earth.
