Warrior Feather

The Warrior Feather is a small feather that attaches to Amy's hairband. This is upgrade is only in Sonic Adventure. With the Warrior Feather, Amy will be able to perform a spin attack with her hammer, but if Amy performs the attack for too long, she'll get dizzy; she won't be able to walk in a straight line and she won't move as fast.

Location
After Gamma frees her from her prison on the Egg Carrier, Amy has to complete a small game. The game is like a Whack-a-mole game, except there are three dolls; a blue doll (Sonic), a yellow doll (Super Sonic), and a Robotnik doll. If Amy manages to beat the current high score, she will be awarded the Warrior Feather.
