A licensed, yet infringing, plush toy of Rudolph. It has the same movements as Rock & Roll Elmo (strumming its guitar and trembling), in addition to head-swaying and a flashing light in its nose.
In addition to this plush toy, there are other infringing Rock & Roll toys which have the exact same mechanism (without a light-up nose ofcourse), such as a knockoff Rock & Roll Ernie, a plush dog, and a plush monkey.
The song it plays is the Mambo version of "Rudolph, the Red-Nosed Reindeer" by Ricardo H.
