Amy: Taking the Leap Together! is the third Challenge Act of Chemical Plant Act 2 in the console/PC version of Sonic Generations. It is unlocked after clearing every Stage in the classic era and is playable only as Modern Sonic.
In this Challenge Act, Sonic must traverse Chemical Plant Act 2, avoiding enemies along the way. However, at certain points Sonic is forced to make impossibly high jumps to reach the next portion of the level. In these instances, the player must call Amy to his/her side by pressing /. Amy then appears in a puff of smoke with her Piko Piko Hammer, which she swings at the ground. The impact shakes the ground and throws Sonic up into the air with his tripping animation. However, Sonic is not sent high enough. In order to send Sonic skyrocketing, the player must press / again immediately before Sonic touches the ground. This causes Amy to swing her hammer once more, and Sonic will fly up into the air again, but this time higher and with his spring animation. The player must repeat this process multiple times throughout the level, sometimes to break boxes and sometimes on moving platforms. Once Sonic reaches the Goal Ring, the Challenge Act is completed and the player is ranked according to his or her time.
- This is the first Challenge Act in which Amy Rose appears.
- After finishing this Challenge Act, Amy will say "They say that teamwork is the cornerstone of marriage, Sonic. I... Hey, wait! Come back!" when talking to her in the White Space.
