M2 really likes having goofy credit sequences in their SEGA 3D Classics line of games, in this one we see each unique enemy type being shown off with a sequence of iterations with either Sonic or Tails. The Tails ones seem to involve him getting hit by said baddies and having Sonic come rescue him.
Sit and appreciate all the different unique baddies with their own animation that Sonic the Hedgehog 2 had to offer. Now I want to play 3D Sonic the Hedgehog 2... I guess we will have to wait until September.
