Bullet Biff

Bullet Biffs (originally known as Gira or Gina ) are a species of Bullet Bills found in Sarasaland in Super Mario Land.

Bullet Biffs look like ordinary Bullet Bills but have rockets on their backs. They can be defeated with a single stomp, earning Mario 400 points. They are only found in the last two kingdoms, Easton and Chai. Bullet Biffs are fired out of Turtle Cannon-like objects known as Pipe Cannons, which pop out of pipes in intervals much like a Piranha Plant. The Bullet Biff that comes from a launchpad travels with a perfectly straight trajectory as usual, but also moves at a higher speed than an average Bullet Bill. Pipe Cannons can be used as a stepping stone to reach high areas. Bullet Biffs are also fired from Roketons if they are passed by, where they are shot diagonally towards Mario's direction.
