From the Super Mario Wiki
Hot Drumsticks, known as Spicy Drumsticks in the instruction booklet, are consumables that can only be used by Bowser in Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. They are the cheapest and weakest type of drumstick, surpassed by the Fiery Drumstick, the TNT Drumstick, and the remake-exclusive Cheesy Drumstick. If eaten, he instantly regains eighty HP. It can be purchased from Broque Monsieur's item shop as soon as it becomes available for ten coins. The Sea Pipe Statue has a 100% chance of dropping a Hot Drumstick after a battle in the original game, Chuboombas have a 35% chance, Toothies have a 30% chance, and Flifits and Treevils have a 5% chance.
