The "Cluckons" are a species of alien who appear in "The Funk". Their planet is invaded by Lord Hater and his Watchdogs, but the invasion eventually fails when Lord Hater suffers a funk. However, Peepers orders the Cluckons to stay still because they're still halfway conquered. This causes them to exchange confused looks as the spaceship leaves.
The Cluckons are chicken-like aliens with white mustaches and greenish tails.
