Dry Bones (also known as Skeleton Koopas) are skeletal versions of Koopa Troopas. These undead Koopas often collapse when attacked, but they soon revive themselves and become normal once again. Dry Bones first appeared in Super Mario Bros. 3, in which they are an edit of a Koopa. They have since become a staple in Mario spin-off games. Dry Bones is ordinarily a lightweight character in games and is often accompanied by Boo. The Dry Bones emblem is a side-view of their heads.
Dry Bones has only appeared in three titles of the Mario Party series. The first game it appeared in is Mario Party 7 as an unlockable, playable character. It can be purchased in the Duty-Free Shop for a price of 1000 Cruise Mileage Points. The Magic Orb is Dry Bones' special Orb which doubles the number on the dice block and then turns Dry Bones invisible. In artwork of the game, Dry Bones is usually partnered with Boo.
Dry Bones reappears in the next game in the series, Mario Party 8, once again as a playable character. This time, it is available from the start of the game.A Dry Bones was seen in the trailer for the upcoming title, Mario Party 9. However, it is a non-playable appearance.
