I have a few questions 1. in sonic advance two i don't now how to get tails or knux I beat the second boss but I didn't get tails or (knux) 2. if shadow dided how is he in the comics and sonic X 3.in sonic adveance 1and2 sonic had the shoes with the stripe and could grind i thought the ones in sa2 were made just fo grinding. sorry for the long question.
1. Keep playing. Tails and Knuckles are available after later bosses.
2. Alternate universes/continuities.
3. That's not a question, but the reason the shoes don't look like those in SA2 is because SonicTeam didn't use SOAP's design again.
