Time Trials Plus
Tails has a boyhood crush on the older Sonic the Hedgehog, and in the middle of the magic Mystic Park, he tries to take his chances with him. But standing in his way is his competition, Shadow; his capricious surrogate sister, Amy; and the time traveler, Silver.
An adaptation of the Gravity Falls episode "The Time Traveler's Pig" into a Sonic the Hedgehog story. It's fun!
