Scatlas

Scatlas is a Bug/Ground-type Pokémon introduced in Generation Neo-I.

While it is not known to evolve into or from any other Pokémon, Scatlas can change its form with its signature ability Neat Freak and become Bug/Poison.

Biology
Scatlas is a golden, beetle-like Pokémon. It has a hard shell, and several thin legs that sprout out from under it. Its head is visible, also protected by hard shell. It is always found rolling a large ball of dirt around with its two large front legs. It is constantly pushing the ball somewhere, though it is not known where nor why. When its signature ability, Neat Freak, is activated, Scatlas will rear back onto its hind legs and get significantly "angrier", flashing red eyes while waving its arms at its opponent. The ball, meanwhile, becomes dirtied and takes on a purple hue, becoming "poisoned".

Triva
Scatlas may be based off of dung beetles, particularly Scarabaeus satyrus, due to their ability to navigate using the Milky Way. They may also be based off of the legend of Atlas, who is commonly depicted holding up a globe, much as Scatlas are known to hold up their mud ball towards the heavens.

Scatlas may be a combination of scat and Atlas.
