Calorite

Calorites are fiery monsters found inside the Flab Zone of Bowser's body in Mario & Luigi: Bowser's Inside Story. They will use the two logs in their hands to increase the power of their flames, and then the Calorite will begin rolling while shooting flames at Mario and Luigi. This attack can be avoided if the heroes simply jump over the flames. If they are hit by this attack, they might get a burn and lose a few turns, unable to dodge or counterattack. The number of times the Calorite rolls is based on the amount of times the logs are tossed into their fire. Calorites are also able to eat Tenderlings and turn them into additional Calorites. They can be attacked by using a hammer and all special attacks except Jump Helmet, Spin Pipe, and Magic Window. If they jump, use Jump Helmet, Spin Pipe, or Magic Window, they will lose one HP and forfeit their turn.

Trivia

 * The Calorite is the only regular enemy in the game that can inflict the Burn status ailment on Mario and Luigi.
 * The fire and burning powers of the Calorite reference the real life calorie, which is measurement of heat used to gauge the energy content of food.
 * Unlike most fire enemies in the Mario & Luigi series, the Calorites are not immune to fire and they take damage from Mario and Luigi's Fire Flower attack.
 * The Calorite could be a reference to the Blazing Shroob as both have rapidly moving legs and both have fire on their heads.
