Rellor is a small, brown, beetle-like Pokémon. It has four horn-like protrusions on its head, and its face is pink with lazy eyes, a bulbous nose, and black curved stripes over and under it that resemble a unibrow and a chinstrap beard. Its abdomen has a rounded yellow pattern, and it has four long limbs, each tipped with two claws. On its back is a random pattern of beige stripes resembling a maze.
Rellor almost always orients itself upside down as it rolls around a mud ball, which is brown in color with random white and orange stripes. Rellor creates its mud ball by mixing dirt and sand with psychic energy. It values its mud ball more than its own life, and rolls it around as the energy needed for it to evolve matures. Its hind legs are strong enough to lift the mud ball over its body.
Rellor appears to be based on a dung beetle, a subcategory of the scarab beetles. The pattern on Rellor's abdomen resembles a cartoony depiction of a feces pile when viewed upside down, alluding to its origin.
Rellor rolls a ball of mud in lieu of a ball of animal dung; this may be a reference to dorodango, a Japanese art form where mud is carefully shaped and polished into a smooth, shiny sphere. Its Shiny form rolls a golden ball that resembles a Nugget, which may be a reference to kin no unko, a Japanese pun that links "golden poo" with "good luck".
Its Shiny form could also be a reference to ancient Egyptian mythology, since the sun god, Ra, was commonly depicted as a dung beetle rolling the golden sun across the sky.
Name origin
Rellor may be derived from roller spelled backwards.
Shigaroko may be derived from a partial backward spelling of 糞転がし funkorogashi (colloquial term for dung beetle).
