Sandile

Sandile is a short, quadrupedal Pokémon with a long snout and tail. Its body is mostly light brown with the exception of black stripes crossing over and under its legs and its pink underbelly. It has a black stripe on its snout in front of its eyes, and black covering the tip of its tail. Its eyes resemble shaded binoculars and are shrouded in black all around their front. The black is a membrane that prevents sand from getting in Sandile's eyes and helps it see in the harsh desert sun. Its long snout is tipped by two protruding nostrils, and its mouth comprises the bottom half. Its feet are flat and contain three sharp, black claws. They are attached to stubby legs on its sides.

Sandile is only found in deserts, with the exception of Alola, where the warm environment is comfortable enough for them to appear elsewhere. Sandile preys on Trapinch. It usually burrows under the surface, with only its nose and eyes above the sand. Due to being so close to the surface, it can move around the desert and allow the heat of the sand to regulate its body temperature. This also serves as a way of hiding from enemies. When the sun sets, it burrows deep into the sand to sleep until sunrise. As seen in the anime, in the wild, Sandile can be mischievous and potentially troublesome to humans. However, Sandile will protect another of its species, and can be caring at times. Sandile is not very good at hunting down prey, thus it mostly eats anything that collapses in the desert or walks near it, hence known as the "Cleaner of the Desert".
