Troupple Grotto - Axolongl Cave is a stage in Shovel Knight Showdown. It is unlocked by defeating 50 Troupples during a match in Troupple Grotto - Royal Pond stage.
This stage is based on the Troupple Grotto from King Of Cards. The stage is primarily made up of several platforms suspended over water with the sides walled off. Several Axolongls move around the stage, acting as moving platforms that can disrupt play.
