Super Bell

The Super Bell is an item introduced in Super Mario 3D World. It is a golden striped bell with beady eyes. When obtained, Mario, Luigi, Princess Peach, Toad, Bowser, Rosalina, or Toadette will transform into their cat form, which allows them to slide into enemies, pounce in midair, and climb up walls and Goal Poles. There is also another power up called the Lucky Bell, which also turns Mario into his Cat form, but when he ground pounds, he turns into an invincible Lucky Cat statue and earns bonus coins while falling.

Super Bells are first seen during the game's prologue scene, where they are flung out of the Clear Pipe leading to the Sprixie Kingdom, along with many other items such as POW Blocks and Double Cherries. Super Bells can be seen again in the Wii U version of Captain Toad: Treasure Tracker, since the same scene plays at the end; however, the items are not obtainable in the main game. In Mario Kart 8, the Super Bell is the emblem of the Bell Cup and a track called Super Bell Subway as a part of the Animal Crossing × Mario Kart 8 downloadable content pack for 2015, and available in the main game in Mario Kart 8 Deluxe.

Super Bells make their debut in a 2D game in Super Mario Maker 2, appearing as power-ups in the Super Mario 3D World level style.

Super Bells replace the original game's Bells in the Super Mario Mash-Up Pack of Minecraft, but without the eyes..
