Mega Monty Mole

Mega Monty Mole is a Monty Mole enlarged by Kamek who appears as a boss in both Mario Party 10 and Mario Party: Star Rush.

Mario Party 10
In Mario Party 10, Mega Monty Mole is the mid-boss of Airship Central in the minigame, Mega Monty Mole's Maze Mischief. During the minigame, Mega Monty Mole arrives on a Monty Mole themed Hot-Air Balloon and the players on their Airship emerge for battle. Players need to make it through a maze on the Airship in order to reach the cannons to fire at Mega Monty Mole, whoever reaches the cannons first gets the better cannon which deals more damage to Mega Monty Mole for more points. After each attack, Mega Monty Mole will pull out a Bomb rearranging the maze giving players a different maze to work with. When Mega Monty Mole is depleted to half his health, every time he rearranges the maze, bombs are also added in certain ends forcing players to avoid them. If a bomb explodes on a player, they lose a point. After his defeat, Mega Monty Mole collapses and then proceeds to explode, releasing several Mini Stars.

Mario Party: Star Rush
Mega Monty Mole later reappears as a boss in Mario Party: Star Rush. In this game, he is fought in the boss minigame Mega Monty Mole's in the Hole and is fought similarly to Lemmy and Wendy in Super Mario World utilizing dummies to fake out players and the fight takes more of a Whack-A-Mole approach. During the minigame, Mega Monty Mole pokes out of the various holes in the grounds alongside his various fused decoys and players (armed with their hammers) have to score hits on Mega Monty Mole to earn points whilst avoiding the explosive fakes (which cause players to lose points). Players must keep an eye on Mega Monty Mole and his fakes in order to succeed, it's generally easy to tell the fakes apart from the real Mega Monty Mole as the fakes don't move and have fuses. When Mega Monty Mole is enraged, more fakes will show up leaving more room for error and picking up the challenge a bit. After Mega Monty Mole's defeat, he explodes once again and whoever has the most points is the winner.
