"Yellmo" is a fictional character, parody and a popular meme created on Drawception. Described to be the weird, psychotic, yellow cousin of the character Elmo (from Sesame Street), its original concept was created on October 25, 2016, by users Crimson Doom and John, Why?. He is friends with Coffee Monster. He has a version of 'Tickle me Elmo' called 'Pickle me Yellmo,' despite being allergic to pickles. Yellmo has apparently hugged Coffee Monster before, and has apparently smoked crack with Cracky Monster before.

Even Adam Sandler endorses Yellmo: https://www.youtube.com/watch?v=Py2f38iPBeI
