In "Slushy", Luki can be seen running the Shave Ice stand and offers both Lilo and Stitch snow cones, even though Stitch initially declined due to being afraid of trying new things. The stand later becomes Experiment 523's (Slushy's) one true place where he makes Shave Ice for people using his ice breath, after he was captured and rehabilitated by Lilo and Stitch.
In "Angel", Slushy is seen again making Shave Ice. Later, Angel appears and sits on top of the stand's counter. She then reverts Slushy to evil again by singing her siren song. Slushy then wreaks havoc while at the Shave Ice stand.
In "Snafu", Slushy can be seen once again making Shave Ice with Dupe. Later, Gantu attempts to revert Slushy and Dupe to evil with a recording of Angel's song, but due to interference from Experiment 120 (Snafu), Gantu's karaoke tape is played instead, much to Slushy and Dupe's amusement.
