Sewer rat
Ricky was the boss of the Macro Zone in the game Super Mario Land 2: Six Golden Coins. He is a rat with a rather prominent nose which he apparently uses for defense. His fight is similar to the battle with Morton Koopa Jr. during the events of Super Mario World. Ricky will run up walls and into pipes, and will eventually crawl to the top of the ceiling and fall straight onto Mario. If the plumber jumps on top of the giant mouse three times, the creature will be defeated. Ricky will then fall off the screen, and Mario will get one of his six Golden Coins.
Ricky (although not named) also appears in the first Mario vs. Wario comic. On his way to visit Wario, Ricky was the first enemy Mario encountered. Mario mistakenly assumed that the rat just wanted to have a party, and ripped his needle-point nose off to use as a kazoo, causing Ricky to faint.
