Numel is a yellow, quadruped Pokémon that resembles a Dromedary camel with a volcano-like hump on its back. The hump is green at the very top and fades out into yellow with small green spots. It contains magma of almost 2,200°F. A female will have a bigger hump than a male. It has bangs on top of its head, sleepy eyes with brown circles around them, and short, stubby legs.
Numel is a very strong Pokémon, having served humans for many years with its ability to carry heavy loads up to 220 lbs. However, it slows down when wet and cannot stand when it is hungry. Due to its dull wits, it does not notice when it has been hit. Numel lives on volcanic mountains.
