C'mere, Goomba

C'mere, Goomba is the hidden second mission of the Boulder Bowl Galaxy in Super Mario Galaxy 2. This mission becomes available after the player has collected a certain amount of Power Stars and when the Mailtoad on Starship Mario gets a letter from the gold Gearmo, who invites the player to a task.

Mission
This is one of the two Gearmo missions that involve enemies. To unlock this mission, the player must first receive a letter from Gearmo saying that it needs help in Boulder Bowl Galaxy. After reading the letter, the player has to go to this galaxy and make their way to the Boulder Planet. Gearmo can be found searching for a Goomba. The player can find one by breaking one of the planet's rock spires where they first land. They can do so by using their Rock form. When the Goomba comes out, it chases the player, who must lead the Goomba to Gearmo's trap. When the enemy is caught, Gearmo thanks the player and reward them with a Power Star. If all the Goombas in the level are crushed or defeated by the player, they have to restart the mission.
