Collection Room

This is a room where you can see any media from the game such as videos, music and art. This collection room first appeared in Sonic Unleashed but it was named as Professor Pickle's Lab. Until in Sonic Generations, it received the name Collection Room. In Sonic Unleashed, you can unlock media by searching for them in day time and night time stages. In Sonic Generations, you can unlock videos and art by completing stages. It's very unknown how to unlock the music in the game but there's a new feature called characters; which features the whole cast of the game and their bio. You can unlock their bio by rescuing them.
