A four-legged white creature with a large head and beady black eyes originally created by the Twitter user @acmeiku. It was popularized by a meme that took the drawing, added a confetti effect, and a voice clip of a child saying "Yippee!"
It became the unofficial "mascot" of the autistic community after a Tumblr user posted it with the caption "so obsessed with that thing, it's like the spokesperson for autism".
