Holly Koopa
- “Well, check you out! Are you my biggest fan? For 50 coins you are! You're a Star in my book!”
- —Holly Koopa, Mario Party 8
Holly Koopa is a female Koopa Troopa who appears to be rather wealthy. She is found during the events of Mario Party 8, on the board Shy Guy's Perplex Express. If the player lands on a ? Space that resides on the top of the train, a Shy Guy will appear, announcing that Bandit or Mowz has stolen Holly Koopa's candy. The player must remember which car they last saw Mowz or Bandit riding in. If the player answers correctly, the Shy Guy will award them coins (20 coins for Party Tent; 10 for Star Battle Arena). Another question mark in one of the rooms has Holly Koopa asking the player if she could buy one of their candies if they have any. She will give the character coins in return (if they give her the piece of candy); which is dependent on the number of coins the candy is from the Candy Shop. For example, if the player has a candy like a Twice Candy, and she asks for it; the player will get 5 coins from her if they say "Yes" to 5 coins for their Twice Candy.
Holly Koopa appears in Star Battle number 4. Here, she plays a major part in the battle. The player who has 50 Coins and trades them to her before their opponent does, will be Holly Koopa's number one fan, get a Star from her, and win.
The Shy Guy conductor of the train states that he has a large portion of money, and that he is a big fan of Holly Koopa; however, he is too shy to meet her. In Star Battle, when the player meets the Shy Guy conductor, he will give the player ten coins to give to Holly Koopa. Template:BoxTop
