Joyous Fish is an animated bump and go toy fish from Zhen Di.
The fish appears to be based on an oranda goldfish, but is bright yellow. It has patches of red below its mouth, on the left and right sides of its head, and one near its dorsal fin. It also has a patch of blue, outlined in white, near its left fin. It has translucent, yellow fins and a tail made from the same plastic. It also has black eyes.
The box features a version of the fish that appears to be red with patches of white on its body, but it isn't known if this version was produced.
The fish opens and closes its mouth, and moves its left and right fins and tail. There don't appear to be videos of it, but it probably plays music, has lights in its fins and tail, and it looks like the eyes are capable of moving?
