Floppers are the weakest type of Slugs. Their element is unknown. They are very lazy. They can shoot a trail of smoke behind them like a Flatulorhinkus. They don't transform but they are useful in a pinch such as when you don't have a Slug. Upon contact, Floppers produce a splat of slime. Eli has one named Noodle that he uses in the episode "Roboslugs". One popular use for Floppers is accuracy training or sparring, as it can't actually hurt an opponent.
