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.
- Bantam Scrambled, Chick Poacher, and Rolly Roll from Billy Hatcher and the Giant Egg make cameo appearances in this track, standing in front of the first fork of the course layout. Ironically, Billy Hatcher himself does not appear.
- 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 and Bang! Bang! Big Hornes Explosion 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.
