Mandibug Stack

"Those red have taken over our blue! Ooooh, they make me so mad!"

- Honeybee

The Mandibug Stack is a mini-boss appearing in Super Mario Galaxy and its sequel. It is a normal-sized Mandibug with a smaller Mandibug on its back.

Super Mario Galaxy
The Mandibug Stack is encountered in the Honeyhive Galaxy mission Trouble on the Tower. To defeat it, Mario or Luigi must first squash the offspring on top with a Ground Pound. Upon doing so, the Mandibug Stack will become angry and approach Mario faster than a regular Mandibug. Ground Pounding the parent as well reveals the mission's Power Star.

Super Mario Galaxy 2
In Super Mario Galaxy 2, the Mandibug Stack is present in the Puzzle Plank Galaxy mission The Puzzling Picture Block (after the puzzle on the final planet is solved). The enemy behaves and is defeated the same as in the predecessor. It shares its boss theme with King Lakitu and Boulder Bowl Galaxy's Prankster Comet mission, which in turn is a variation of Baron Brrr's boss theme from Super Mario Galaxy, unlike the first game, where it has no theme at all. Along with Bugaboom, the Mandibug Stack is one of the only two bosses originating from Super Mario Galaxy to reappear in the sequel but to not be fought in the Boss Blitz Galaxy.
