Nutskis are enemies from the Kid Icarus series.
Nutskis appear as enemies in Smash Run.
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.
