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. Calorites are also able to eat Tenderlings and turn them into additional Calorites.

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.
