Yellow Wollywog

The Yellow Wollywog is a surface species of Amphituber commonly found on PNF-404 by numerous explorers to the planet.

Description
Yellow Wollywogs are amphibious creatures resembling frogs, and have a lot of similarities to the creature in question. It's notably taller than Wollywogs, and more found around above ground instead of underground like their subterranean cousins. They have yellowish, smooth skin with slightly green tops as a slight camouflage.

Recent studies during the Rescue Corps expedition reveal that the Wollywog's true size can reach around the size of a Bulborb, though these individuals are of advanced age. Due to their larger size they have a difficult time hopping around, but their signature attack is strong enough to leave an indent upon landing.

Behavior
Often found within shallow pools of water, many explorers note how aggressive these creatures are as they will jump and try to crush them underneath their surprisingly heavy bodies. They inflate an air sac underneath their bodies when they jump to stay afloat briefly, releasing the air soon as they're above their targets to crush them below. At first it was just jotted up to territorial anger, but studies had shown they only become this aggressive when creatures venture too close to their eggs, making them less of an aggressive creature and more of a very protective one.

Its protective behavior is understandable, as many young Yellow Wollywogs are prey items to many other creatures.
