Chao in PSO

[cOoLdUdE]

You can find PSO item boxes in SA2 -- Rouge's final stage, Mad Space.

There's no 'world' correlation, it's just that all games belong to ST.

And yes you can see Sonic, Tails, Knuckles and Eggman on Pioneer 2 on certain days (usually around Sonic's anniversary, or when a new Sonic is out).

There's also the Egg Launcher that's a reference to Sonic, and Samba Maracas a reference to Samba de Amigo, etc.

Yes they do come out sometimes but when nothing is happening and u see a miniture sonic or redring rico ect. those are hacks.
FYI this only happens in vega where normal players are sonic
