Rescue the Animals 2! is the fifth and final Challenge Act of Planet Wisp Act 1 in the console/PC version of Sonic Generations. It is unlocked after clearing every Stage in the Modern era and is playable only as Classic Sonic.
The Act is similar to the normal version of Planet Wisp. The player begins inside the factory, climbing upwards while opening Capsules and avoiding the Bombs dropped by the Sprinklers. The player will eventually drop down to a lower section, continuing to travel through the factory's interior until they reach the Goal Plate.
