Easter Egg - Extended Frog Forest | |
| Go to Frog Forest with Team Rose. When you reach the goal ring, let the frog close to it make the rain fall. This will cause a vine close to the goal ring to grow. Use Team Blast to to increase your speed. Then switch to fly formation and grind on the vine as fast as you can, jump at the end of the vine and try to fly to the other side. Now you can play the extended version of Frog Forest. | |
Easter Egg - Extended Casino Park | |
| Get to the goal ring with Team Rose. Use your team blast to increase your speed. Go on the "railing" on the platform you are on and try to fly to the other side. You can now play the extended version of Casino Park but you will not be able to go to the VIP room. | |
Easter Egg - Extended Bullet Station | |
| Get to the end of the stage with Team Rose. Get on the rail as Cream, and at the rail's high point, jump off and fly towards the triple-rail above/ahead of the ring. (Cream must have advanced to level 3 in order to do this correctly.) You can now play this stage for a while longer as Team Rose. | |
