Pouncer

Pouncers are stone creatures from Wario Land: Super Mario Land 3. They look and behave almost exactly like Thwomps, except they have no spikes on their tops. Wario can hop up on them as a platform to cross gaps. In some cases, instead of acting like Thwomps, they slowly follow a path, such as moving through a cramped hall after Wario. If a Pouncer lands on an enemy, it turns into a 10 Gold Coin for Wario to collect. On the other hand, contact with a Pouncer's spikes instantly causes the loss of a life.

In Wario Land II, redesigned Pouncers make an appearance, referred to as weights or blocks. They are have no spikes and are carried and routinely dropped by D-Bats. They are no longer harmful, transforming Wario into Flat Wario if it lands on him.
