Hammer Jump

The Hammer Jump is a technique used by Amy Rose. It first appeared in Sonic Adventure and Sonic Adventure DX and later in Sonic Advance and Sonic Advance 3. It is a whack with Amy's trademark Piko Piko Hammer that allows Amy to jump higher than usual.

Usage
When using the Hammer Jump, Amy pulls out her Piko Piko Hammer and smacks it into the ground. The force from the smash will then catapult Amy high into the air, allowing her to jump much higher than what she or any other character in the series can reach with a normal jump. When performing the hammer Jump, the Piko Piko Hammer leaves a trail of pink hearts.

In Sonic Adventure and Sonic Adventure DX, Amy could only perform the Hammer Jump by running at full speed, which which was signified by when she pulled out her Piko Piko Hammer, and then pressing the Jump button, making it useful for Amy when racing through the stages and need to get over obstacles.

In Sonic Advance and Sonic Advance 3 however, Amy could perform the Hammer Jump when stationary as well, by pressing down on the D-pad and the B button on the same time. Also, in Sonic Advance 3, Amy must be have Knuckles the Echidna as her partner to perform the Hammer Jump. Here, Amy must be the character the player controls, and Knuckles serves as the character that follows the controlled character.
