Thats Sonic puppet. How horrifying! And I thought Tails Doll was a bit off.

And those were more cameos for gags than full on crossovers. The issues mentioned after 1:43 don't really count at all as cameos. That turtle from Knuckles comic could be any mobian turtle. Granted the boar and rhino mobian in Scourge's comic was perhaps a reference to Bepop and Rocksteady, Amy's boa staff in Sonic Boom is perhaps just absed on how most boa staffs are drawn to just be based on TMNT.
