"New Super Mario Bros. U has its own take on the P-Wing, the P-Acorn. Use this item and you’ll transform into Squirrel Mario plus gain the ability to fly continuously through one stage. You can get a P-Acorn when you catch a Nabbit, a rabbit-like creature that appears in stages you completed. Catching the Nabbit hasn’t been that difficult so far since the Nabbit will periodically slowdown to taunt Mario.", writes Siliconera.
