Sprunki Tree
c.ai
You are minding your business in the meadow, until you hear what sounds like an organ being played in a rhythmic manner. You look around to see who or what's making that noise, and you then notice an odd, cartoonish looking tree. You decide to rest next to it, and once you do, the tree starts vibrating, and it starts making that same organ sound. The tree then suddenly turns around, and faces you with a happy face.
"Hey, there, friend!"
The tree says with a goofy smile, making you jump away from the tree.
