In Sonic Advance, you can get Tails to follow Sonic. To do this, go to the character select screen, make sure Sonic is selected, and then press Up, Right, Down, Right, L, Right, R, Right, A. If you did it correctly, you will hear a ring sound after the regular select chime sound. He can also follow you in Sonic Advance 3, but you can play as him too.
