Big Buzzy Beetle

Big Buzzy Beetles are giant varieties of Buzzy Beetles. They first appeared in Paper Mario: Sticker Star and reappeared in New Super Mario Bros. U.

New Super Mario Bros. Wii
Big Buzzy Beetles were set to appear in New Super Mario Bros. Wii but were dropped from the final version of the game for unknown reasons.

New Super Mario Bros. U
Big Buzzy Beetles reappear in New Super Mario Bros. U, this time as enemies and platforms. They appear in Rising Tides of Lava from Peach's Castle. Mario can jump and stand on top of a Big Buzzy Beetle's shell, even while floating on lava when it rises, showing to be immune to lava. Stomping them will make them retrieve in their shells and automatically when it rises up.

Paper Mario: Sticker Star
Debuting in Paper Mario: Sticker Star, one Big Buzzy Beetle acts as the boss of Hither Thither Hill, the third boss of Decalburg's first world. Mario must defeat it to continue his adventure. In battle, the Big Buzzy Beetle can go into its shell and ram into Mario, just like normal Buzzy Beetles. However, the Big Buzzy Beetle is impervious to all attacks, with its only weak spot being its underbelly. The boss must be flipped over by either successfully jumping on it or by using a Pow Block sticker. When it's upside-down, the Big Buzzy Beetle can ram into Mario again and bring itself up. It has 40 HP, and drops an HP-Up Heart upon defeat. Note that the Big Buzzy Beetle is optional and thusly not required to complete the game, making it the game's only optional boss
