Tickle Me Elmo's fire

Tickle Me Elmo's fire is an electrical space phenomenon in which luminous plasma attaches to and covers objects passing through the Bermuda Tetrahedron. It is red-colored, just like its namesake. The Planet Express crew encounters it on its voyage through the Tetrahedron in "Mobius Dick".

Trivia

 * The phenomena's name is a parody of St. Elmo's fire, its terrestrial equivalent, and the Tickle Me Elmo doll, based on the Sesame Street character it depicts, named Elmo
