Trick Island

High-Speed Hijinks 2 is the third Challenge Act of Seaside Hill Act 2 in the console/PC version of Sonic Generations. It is unlocked after clearing every Stage in the Dreamcast era and is playable only as Modern Sonic.

Overview
This act takes place within a highly modified version of Seaside Hill Act 2. Additional platforms, Rainbow Rings, and Trick Jump Panels have been placed throughout the stage, changing the layout entirely.

Description
In this Challenge Act, the objective is to reach the Goal Ring at the end of the course after performing at least 35 Trick Actions. The player begins on one of the giant Sea Turtles, and will eventually progress onto the race track segment. The player will be taken above the beach outside the temple, then through the temple, and outside again toward the end of the normal Act where the Goal Ring lies.
