The Harp is a rare item appearing in both Kid Icarus and Kid Icarus: Of Myths and Monsters, where the effect is similar between games. Upon collecting the Harp, it turns all on-screen enemies into slow-falling Mallets, even affecting those who enter the screen during the short-lived effect. Pit will only find this outside of Fortresses. The effects of the Harp only last for a few seconds, but transmuted foes will remain as Mallets even after the Harp stops playing. Transmuted Mallets can still be destroyed for Hearts as though they were enemies, but this only applies to Mallets created through the Harp. Harps will disable a Shemum's Jar from spawning more Shemums until the effect is over.
