This is my interpretation of Adder's Lair that comes from Sonic & All-Stars Racing Transformed, but originates from Golden Axe. The track is partially represented by the boat and plane rides as a reference to the transforming mechanic of the game. The plot has plenty of cut-offs to allow you to check the cave sections, so it's not required to use the cut-away view. I highly recommend to check the plot while listening to the following song: https://youtu.be/SZSoukNb1Xk
