Tail Bullet Bill
From the Super Mario Wiki, the Mario encyclopedia
As with most Bullet Bills, they are fired from Bill Blasters, and fly in the direction they are fired from; unlike normal Bullet Bills, they will briefly slow and do a spin attack with their tails after traveling some distance. After defeating a Tail Bullet Bill, Mario sometimes can obtain a Super Leaf (Statue Leaves in Special World levels).
