The Tribble-Like Creatures were a group of pets owned and trained (for six months) by Sidney. They were depicted as colorful, mischievous balls of fluff that would mess up Sidney's room frequently.
Unfortunately, after being thrown out by Sidney for what appears to be the millionth time. A barrel pushed by Arthur goes out of control, breaks through the ceiling and heads towards the creatures, crushing them in the process. Their flattened corpses are eaten afterwards by Trevor.
- During the scene where the creatures are messing up Sidney's room, there are eight to nine of them. But in the next scene, there are only six or seven. This can lead to the implication that some of the creatures are still alive, only missing or off-screen.
