Touching a thorn immediately causes a [[Yoshi (species)|Yoshi]] to lose a life. A [[Yoshi's Egg|Yoshi Egg]] destroys a single thorn, but since thorns are found usually in groups and a Yoshi can carry only six Yoshi Eggs at a time, most thorn groups cannot be destroyed, though [[Baby DK]]'s explosive eggs in ''Yoshi's Island DS'' can easily destroy a group of them in one shot. Some thorns reveal [[Winged Cloud]]s when destroyed, and in [[The Potted Ghost's Castle]], one specific thorn reveals even a door.
