Canon has always been up in the air with the Sonic franchise, we have Shadow who "died" in Sonic Adventure 2, but was brought back because of his popularity.

Also we have characters like Fang, Mighty, Ray and all those other Classic era characters that simply disappeared with no explanation (Except possibly Generations where they are apparently labeled missing).

Then you've got the comics and cartoons which have nothing to do with the canon of the video games and have their own canon, which possibly might confuse some people.

Then we have Sonic Spinball which has the game take place on Mobius in all localizations and with some of the old cartoon cast in it's bonus stages.

Pretty odd that Toxic Caves' music from Sonic Spinball managed to get in Generations as well.
