Tsubōn

Tsubōn are pot-shaped enemies with a skull mark in Mario & Wario. They are stationed on walls and ceilings, and routinely spit fireballs. They are sometimes found hanging on breakable obstacles such as Rock Blocks, so Wanda can simply crack or disable their foothold, making them disappear once they hit the ground. However, some Tsubōn must be passed at sections such as elevators or holes, which requires careful timing to get her helpless character by them. Wanda can also hit their projectiles to neutralize them, or hit the diagonal-facing versions on some ceiling to get them to aim in another direction. They are most prominent in LEVEL 5, where they appear in every area.

In Super Mario-kun volume 10, it is revealed that the Tsubōn are cursed people who drink the Blargg's mysterious soup in a bucket inside the fire cave.
