The Chimp's Score Challenge

The Chimp's Score Challenge is the hidden second mission of the Honeyhop Galaxy in Super Mario Galaxy 2. This mission will become available after the player has collected a certain amount of Power Stars and when the Mailtoad on Starship Mario gets a letter from The Chimp, who invites the player to a challenge.

Mission
After receiving a letter from The Chimp, the player can do a Stomp Challenge in the Queen Bee Planet. The player must defeat enemies to score ten thousand points or more in one hundred twenty seconds. If the player completes the task, The Chimp will reward them with a star. There are many enemies near Queen Bee that can be stomped on in a row.
