Darumaka is a round, red Pokémon with an orange face and yellow curly eyebrows. It has three yellow ovals on its abdomen and a curvy yellow line on its back. Its paws are orange and have three digits each. It has very warm droppings, which ancient people put in their clothes to keep themselves warm.
When the flame inside its body burns, Darumaka is very active. It cannot calm down in this state, and thus becomes uncontrollable. As the flame shrinks, it falls asleep. It can tuck in its arms and legs when it rests; during that time, it slightly sways. While it is sleeping, it cannot be tipped over no matter how much it is pushed or pulled, like a tumbler doll, which it resembles in this state. It prefers to live in a desert environment.
A Darumaka appeared in PK22 alongside Drilbur and Gothita, in which it was angry at Oshawott and Tepig, who had eaten the apples that the three had collected.
A Darumaka appeared in The Case of the Missing Pokémon, where it was one of the Pokémon kidnapped by Team Plasma. It was later returned to its Trainer after being found in a stronghold.
