The Snuffleupagus Fairy appeared in a story called "The Sock-maker and the Snuffle-upagus," first published in The Sesame Street ABC Storybook. The Snuffleupagus Fairy comes to the homes of sock-makers late at night and makes socks for them. Big Bird meets the Snuffleupagus Fairy when a sock-maker sleeps, and the fairy makes enough socks for the sock-maker to give the townspeople and a mess in the sock-maker's workshop.
When the sock-maker wakes up, Big Bird asks The Snuffleupagus Fairy to stay so that the sock-maker can meet him, but he tells Big Bird that Snuffleupagus Fairies don't stay to be thanked and quickly disappears before the sock-maker shows up.
Unlike other Snuffleupaguses, the Snuffleupagus Fairy walks on his hind legs.
