Flying Battery Music

In both Sonic 3C prototypes, the echo track of Flying Battery Zone's Act 1 music will go off sync after two loops, and slowly gain drag behind the lead melody.

Flying Battery Boss

While playing as Knuckles, in Flying Battery Zone act 2, the boss is Robotnik instead of Egg Robo.

Knuckles in Carnival Night

While playing as Knuckles, one can take Sonic's path in Carnival Night 2, then glide over the boss area revealing a load of junk.

Knuckles Palette

Due to palette limitations, Knuckles' socks change colors; when you are playing as Knuckles, they are green. When you are playing as Sonic, Tails, or Sonic and Tails, they are yellow. Furthermore, as can be noted by entering Sky Sanctuary Zone act 1 as Knuckles through cheating, the two 'versions' of Knuckles have slightly different hues.
