Nick's Sprites and Tiles

Yeah, I played Tails Adventure in Sonic Gems Collection and it's actually a good game. Speedy is Tails' Metal Sonic in where he is his rival, but you race him while flying up Polly Mountain. Even to this day, Speedy is probably Tails' true rival.
I never got to the final boss, but I like how his design is typically 'Sonic' without the usual proportions and facial features.
