Attack Ghosts are giant, crudely made enemies in Yoshi's Crafted World. Resembling giant cardboard Boo Guys with red bodies, a golden scythe, and a Shy Guy mask with evil, purple eyes, Attack Ghosts make their only appearance in Haunted Maker Mansion, the second level of Cardstock Carnival. They only appear twice in the level, both times outside.
Attack Ghosts first appear in the middle of the level, in a brief outside area. Their presence is not immediately clear, but when the Yoshi is near one, it suddenly appears, marked by a ghoulish laughter, and it proceeds to relentlessly chase the Yoshi down, rapidly swinging its scythe. It reappears on the path to the goal. This enemy is invincible, and eggs only push it back; however, there are some arches of stones that can provide some protection against the scythe.
