Agamemnon Mouse is a fan made Easter egg on Abandoned: Discovery Island.
He appears to resemble Mickey Mouse except he has a wide head with a wide mouth with a rainbow inside it. He also appears to be shorter and wider than his normal counterpart. He has arms with two, big gloves clenched together. He also has short legs with gloves as feet.
He only appears in his own night called " Agamemnon Night" if the player types in " Agamemnon" on the main menu.. He starts in Character Prep 1. When he's active, funky music will start playing. When in the office, the player must shut off a camera or he will kill you. While active, he will say things like " Wanna make a new friend?", " Let's have some fun", " This is a happy world" and " Let's make a new friend".
Agamemnon Mouse starts at Character Prep 1, then goes to Staff Area, Meat Freezer, Lounge, and then the office.
He's a parody on the character from a Youtube video, " Agamemnon Counterpart".
