A Koopa's Revenge Wiki


A screenshot of Monstario.

'Princess Musclegum is a form of Princess Bubblegum. she is the Final Boss if all Special Coins aren't collected. In order to defeat her, the player will have to wait until she stands on a crack on a bridge causing her to fall.


Princess Musclegum can punch the ground to send out candy corn spikes, and if the player is close enough to Princess Musclegum, she jumps up towards the Player. If the Player is not close enough for Princess Musclegum to lunge at, he sends jellybeans into the air and may also shoot a chocolate laser. If the Player stands behind her, she will fart causing the Player to fly off the bridge.

How to Defeat[]

Princess Musclegum will surprise the player and the player must lure her to the crack in the bridge. When the Player goes too far, she will throw fireballs that rain down onto the bridge, punch the ground to spawn moving spikes, or shoot a big chocolate laser. The player must stand close to her to make her lunge. She will repeat these moves until she is on the cracked part of the bridge.


  • Monstario will be immune to any attacks the Player uses against him. The only way to kill Monstario is by luring him towards the cracked part of the bridge.
  • If the Player uses the Bone Petal, it will make the player immune to fireball and fire laser attack, but not the spikes.
  • If the player goes to the left pipe (which they used to exit Mario's castle and reach the bridge), Monstario will surprise the player just like he did before the battle began.
  • If you gain enough speed with the cape-feather and manage to get behind Monstario, he will fart and send Koopa off the side of the battlefield. The same feat can be executed if the player uses Rush Coil or Space Jump. (Don't believe me? Try it out.)
