Factual error: When Emma freezes the water in Elliot's shower, frozen water continues to fall on Elliot. This is not possible because Emma only froze the water Elliot was using. Water would still come out of the shower head, but ice comes out instead. Arguably, Emma could be freezing the water in the pipes, but if she did that, nothing would come out of the shower.
Continuity mistake: Near the end of the episode, when Rikki falls over after growing her tail, she falls forward. But, in the next shot, she is lying on the ground face up.
Pool Party - S1-E2
Other mistake: After Cleo transforms into a mermaid, her wetsuit doesn't disappear for some reason.
Answer: No explanation was given as to why his character disappears. As to the actor who played him, Christopher Poree, this appears to be his only acting credit, and he retired as an actor following his time on the show. There is little online information about his personal or professional life and none that I could find on why he left the show.
