Sonic & All-Stars Racing Transformed
Chilly Castle is a track that appears Sonic & All-Stars Racing Transformed, representing the Billy Hatcher series.
The track starts on a snowy day in Icicle Valley. After taking a ride through a village (with cameos from Rocky and Pocky), the player comes across a tunnel, which is actually an illusion. The player instead drops down into an underground river, which deposits the player at the finish line.
- The track itself takes place in Icicle Valley.
- The different colored eggs in the underground boating section were used in Billy Hatcher and the Giant Egg.
- The music is a remix of Tumbling Xylophone from Billy Hatcher and the Giant Egg.
The music is a remix of the Day 2 theme of Forest Village, which then transitions into the same game's boss theme.
