Bullet

In Rayman Legends, a bullet appears when a Hunter shoots his gun from spotting Rayman. They can't be defeated, so Rayman has to either jump or duck to avoid getting hit. The speed of the bullets are relatively slow, but their range is wide; Rayman is likely to get hurt if he doesn't react to them.

Notes: It is unknown if you can use the blue ones as a platform; I say, Go Try It!
