Super Star

Super Star is an animated sound-activated toy dolphin sold by Sun Kee Toys. It requires three AA batteries. While there are versions of the toy without the guitar, the ones with the guitar sway their heads left and right, strum their guitars, and move their mouths.

Versions

Super Star

It was sold by the company with a blue rectangular base that has the letters “Sea World” on it. These ones play an excerpt of “Hotel California”, and then switch to a MIDI cover of the song. When they’re finished with their performance, they play a soundtrack of a cheering audience with someone’s voice thanking the audience.

The dolphins for this version of the toy are known to have been sold in gray and white, pink and white, and blue and white.

"Show Time" Version

I don’t know if Sunkee sold this version or another company, but it does have the same functionality as the “Sea World” ones. Its base is silver and it has the words “Show Time”.

"Funk" Version

Likely sold by a different company. I don't know what this was officially called.

It plays an excerpt from three Brazilian "Funk" songs, including "Dança da Motinha", "Vou Passar Cerol na Mão", and "Tapinha" (thank you so much to @brush-it-gently on tumblr for identifying them).

Guitar-Only Version

From Sun Kee. I've never seen this one's box, so I don't know what this one is called. It plays a short excerpt from “La Isla Bonita” and then plays a MIDI tune.

Confirmed to come in gray and white, pink and white, and blue and white.
