Melissa

From Muppet Wiki

Melissa and Her Magnetic Moose appear in episode 519 of The Muppet Show. Although Scooter has warned the first two rows of the audience to hang onto their fillings, Melissa makes it off the stage with a set of antlers full of wrist watches and car keys.

Although he is not named in the sketch, other than Melissa's sidekick in their routine, the magnetic moose is Mickey Moose.
