Baddie Box

Baddie Boxes are blocks appearing in Super Mario 3D Land and Super Mario 3D World. They are dark olive-green boxes with dark yellow borders and Bowser's emblem in red printed on its sides. When approached, the Bowser symbols will pulse red (doing so only three times before opening in Super Mario 3D World) and the box will release an enemy, though they will stop creating enemies if they have released three that are still on-screen. Defeating these enemies will cause the box to generate more to replace them.

They are semi-rare, appearing in World 2-4,, Special 1-3, and Special 8-3 in Super Mario 3D Land. These blocks release two kinds of enemies: Goombas in World 2-4 and Special 1-3, and Dry Bones in World 5-Castle and Special 8-3. They can be destroyed by the White Tanooki or Statue forms, or while Mario is invincible, although Baddie Boxes are typically found above hazards such as an abyss or lava.

A glitch can occur when White Tanooki Mario ground pounds; it prevents him from falling through the box, which explodes, and the game starts to lag. This glitch can be done by Statue Mario or Luigi in Special 1-3, for example, because the Baddie Boxes are sitting on a platform instead.

In Super Mario 3D World, Baddie Boxes only appear in Bob-ombs Below, Bowser's Bob-omb Brigade and Super Block Land, and they only release Bob-ombs. They can also be destroyed by Lucky Cat Mario.

These boxes are similar to the enemy-releasing pipes and jars in the 2D Mario and Yoshi games, though those usually cannot be destroyed.
