Matt appears as one of the Coral Cuties models on the magazine that Pearl is reading in "Mall Girl Pearl."
Based from the picture pointing to him shown on the cover of the magazine, he is a light-blue colored fish with purple smooth hair, and wears a blue t-shirt with the number "5" written in white on it.
He appears only on the cover of "Coral Cuties." It is unknown whether he will make an actual appearance in the show as of yet.
