P Flying Squirrel Mario,[1] also known as Power Squirrel Mario,[2] is one of Mario's many forms, originating from New Super Mario Bros. U. The form is activated by using a P-Acorn. As P Flying Squirrel Mario, Mario has all of the abilities of Flying Squirrel Mario, though he never loses the ability to glide and can perform Flying Squirrel Jumps continuously without landing. Mario loses the form once he takes damage, loses a life or completes the level; the latter turns him into Flying Squirrel Mario.
Also, in New Super Luigi U, a Mii can use this power-up if the player holds down on the / or on the while selecting the Flying Squirrel Ovation level when powered up with a P-Acorn.
