A lot of Team Rose's levels end at a much earlier point than Team Sonic and Dark's. However, through the use of glitches, exploits, or cheats, it's possible to go past the goal ring with Team Rose and go to areas that are only accessible to the two other aforementioned teams. The same thing can also be done in some of Team Chaotix's levels as well.

Interestingly, the characters of both Team Rose and Chaotix have fully voiced and functioning dialogue for these normally inaccessible areas.
