- Red Boo

Red Boos, also known as Pink Boos due to their coloration, are a light red or pink colored variants of Boos that appear in the Mario Party series. They are treated and behave similarly to white Boos, with the only difference being their coloration in most depictions. Starting with Mario Party: Island Tour, their role of an alternate behavior for Boos has seemingly gone to Peepas.

Boos similar in color to Red Boos have appeared in other Mario games—namely the third Boo raced in the You VS. Boo mode of Super Mario Bros. Deluxe, Boo's second-player color scheme in Mario Tennis, and red-colored Boos in the Mario Party Advance minigame Boo-Bye and the Mario Party DS minigame Peek-a-Boo. However, Red Boos are considered distinct entities from these Boos.

Mario Party 4
In Mario Party 4, Red Boos are mainly featured on the board Boo's Haunted Bash. On that board, a Red Boo appears in the center of the board. Any player who passes it will make both the Red Boo and the Red Boo bridges disappear. When another player passes by it, the Red Boo and the bridges will reappear.

Mario Party 5
In Mario Party 5, Red Boos appear in Card Party. If someone finds one, it steals one of finder's star cards and gives it to someone else.

Mario Party 6
In Mario Party 6, a Pink Boo appears in Towering Treetop and Castaway Bay. These Pink Boos are female, and they speak in stereotypical valley girl jargon. They have the same role that the standard white Boo does in the first four Mario Party games. If it is nighttime, she offers to steal either a star or coins. Pink Boos also appear in the minigames Boonanza! and Boo'd Off the Stage. The ones in Boo'd Off the Stage, however, are gaseous forms of these Boos. Pink Boos also appear in the background of the Star Sprint stage, Dark Path.

Mario Party 7
In Mario Party 7, if a Pink Boo Orb is thrown onto a space, any opponent who lands on it will have a Star or Coins stolen by a Pink Boo and given to the owner of the space. Pink Boos also appear in Mathemortician, where they are worth one point each when shot while the crowned variants are worth three, and in Ghost in the Hall, where they are referred to as Red Boos by the minigame's advice section.

Mario Party 8
Red Boos reappear in Mario Party 8 in King Boo's Haunted Hideaway. These Boos sell Candies to the player. They also throw the player out of the mansion whenever the player reaches a dead end, and they fly out of the chests and steal 10 coins from the player if they open one. Red Boos also appear in minigames such as Boo-ting Gallery with a "big" Red Boo and Specter Inspector.

Mario Party 9
Pink Boos were originally going to make an appearance in Mario Party 9, but were scrapped from the final game.
