The "Elmo on fire" meme, which is sometimes referred to as the "Elmo Eclipse" meme, originated from a scene featuring Elmo in the 1999 PBS special "Sesame Street: CinderElmo," where Elmo is seen dancing in front of a CGI fire effect. This image later became known as "Hellmo" due to the disturbingly jolly image of Elmo with the raging fire in the background.
After an image of this scene was posted online, it circulated widely and became a popular meme format, often used to convey a sense of calm or oblivious enjoyment in the midst of chaos or intense situations.
The "Elmo Eclipse" term came from a particular incarnation of this meme, in which the image of "Hellmo" is superimposed onto an image of an eclipse, further playing on the theme of a humorous or absurd image juxtaposed with a dramatic backdrop.
