Nutskis are enemies from Kid Icarus: Uprising. They resemble one-eyed acorn-like creatures, and have a pair of leaves on each side, allowing it to fly.
In Super Smash Bros. for Nintendo 3DS, Nutskis appear as enemies in Smash Run. They fly in a quick, erratic pattern and attack by turning upside down and firing either a single big projectile or a barrage of smaller weak projectiles. The game has a trophy of Nutski showing three of them.
Super Smash Bros. for Nintendo 3DS trophy information
A grunt in the Forces of Nature from Kid Icarus: Uprising. It was created by Viridi when she removed a chestnut from its shell and blessed it. In Smash Run, they move quickly and in difficult-to-predict ways. When fighters get close, they'll flip upside down and fire three seeds. These great-tasting grunts from the Forces of Nature in Kid Icarus: Uprising came to life when they were blessed by Viridi. In Smash Run, they move quickly in a jittery, off-kilter way. Get close, and they'll turn upside-down and fire seeds at you. Occasionally those seeds will do a lot of extra damage, so watch out!
