The series focuses on the adventures of a half-human, half-oyster mutant named "Boyster", who was born from a toxic spill and adopted by a pair of humans and raised with his shell brother Shelby. Naturally, Boyster has to keep his oyster side under wraps, but he will use his many oyster-esque abilities to save the day.
