The title is partly self-explanatory. It's a knockoff from an unidentified company, based on Lucky the Lobster by Gemmy.
The lobster is a brighter shade of red than Lucky, and it rests on an elliptical wooden plaque with a gold name plate which reads, "SINGING LOBSTER" in italicized capital letters.
He sings "Limbo" and "Pretty Fish", and he says some phrases. He flaps his tail, raises his head, and he has a mouth mechanism inside his head which moves as he speaks. However, since there is no moving mouth piece on the lobster itself for the mechanism, the front of the lobster twitches as he speaks or sings.
