Big Buzzy Beetle
From the Super Mario Wiki
Super Mario series
New Super Mario Bros. Wii
A giant Buzzy Beetle appears as an unused enemy in New Super Mario Bros. Wii, suggesting that they were going to appear during gameplay but were either never implemented into any level or removed before the final release.
New Super Mario Bros. U
While not as large as the New Super Mario Bros. Wii design, Big Buzzy Beetles did eventually appear in New Super Mario Bros. U. They are found in Rising Tides of Lava from Peach's Castle, where they act as both enemies and platforms. Mario can jump and stand on top of a Big Buzzy Beetle's shell while it is floating on lava when it rises, showing them to be immune to lava. When not floating on lava and when it is not stomped on, it just retreats into the shell. They are one of the few enemies that do not reappear in New Super Luigi U.
Super Mario Maker / Super Mario Maker for Nintendo 3DS
Big Buzzy Beetles are present yet again in Super Mario Maker, Super Mario Maker for Nintendo 3DS, and Super Mario Maker 2. The player can enlarge a normal Buzzy Beetle with a Super Mushroom, and thus the implication of Big Buzzy Beetles within the game.
Paper Mario series
Paper Mario: Sticker Star
Debuting in Paper Mario: Sticker Star, one Big Buzzy Beetle acts as a mini-boss of Hither Thither Hill, the third boss battle 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 (except for Ice Flowers, which will damage it), 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. It is also an optional mini-boss, the only one in the game.
