ToeJam & Earl

Mailboxes are found on most floors and usually you can buy presents from them with your Bucks. Later into the game however there will be some mimics that attack you, look out for the eyes in the mail-slot. If you get too close they charge you and are almost impossible to beat, but if you spot one keep your distance and use tomatoes or the slingshot until he's defeated. He should just stay still and take the punishment if you don't get too close, once he's popped so does the trophy.
