Slugma are fiery Pokémon that appear to consist entirely of magma. They resemble slugs, with a pair of bright yellow eyes on short stalks and a small mouth. The magma inside its body acts as a circulatory system, transferring vital nutrients and oxygen throughout their bodies. Its height is 2'04" and weight is 77.2 lbs.
Slugma have to keep moving in order to keep warm; if they stopped moving, the magma would cool and become rock, which would eventually break off and reduce this Pokémon's size. For this reason, they never sleep.
Naturally, Slugma prefer warmer regions where they can keep their magma hot, so they are often found in volcanic regions, such as Mt. Chimney.

It is not known what these Pokémon eat, but they presumably consume soil and rocks to both keep the volume of their magma and collect vital nutrients for their bodies.
Slugma made its debut in the anime as one of Macy's Pokémon in Love, Pokémon Style and was used in her battle against Ash in the Silver Conference. At the end of the episode, it had evolved into Magcargo.
