P-Acorn

A P-Acorn is a item in New Super Mario Bros. U. It transforms its user into P Flying Squirrel Mario with the ability to midair jump indefinitely for the entire stage, similar to the P-Wing and Cape Feather from previous games. Its appearance is similar to the Super Acorn, but the top is pale white and gray-striped, with a large, red "P" imprinted on it, which stands for "power". In Mario's case, his hat and shirt become pale gray; his hat has a large, red "P" instead of his "M" emblem; and he also appears to have a sheen around him. The P-Acorn's power will perish if the player dies, takes damage, grabs a non-Acorn power-up, or completes a level without losing the power-up (the latter of which causing the player to change back to the regular Flying Squirrel form). However, the player will not lose the power-up if the course is completed via capturing Nabbit.
