Didn't know whether to call this page "Lay Egg Fun Carp" or "Fun Carp". This bump and go toy fish was sold by XuanRong.
It resembles an oranda goldfish with a slightly translucent, neon orange tail and more translucent, neon orange fins (it has a small pair of fins closer to its tail which are white though). The fish has a red face with black eyes and its body mostly has white scales with red markings. The bumps on the fish's head are made from the same plastic as its orange fins.
The box shows a version of the toy with a yellow body instead, but I haven't seen any actual photos of this one, so I don't know if it was released.
The plastic cover on the fish's head, resembling bumps, can be removed to add plastic eggs which come with the fish. The fish will play "Witch Doctor" and move across surfaces on its wheels, while moving its left and right fins. It has flashing lights which illuminate its head, left and right fins, tail, and eyes. It will also stop repeatedly and lay eggs, when moving around and playing music.
