I forgot the name of this animation/movie/book and I’ve been looking for it for ages, at first I thought it was some type of hallucination from when I was 4-5, I’m pretty sure this used to stream on tv around Christmas time but it was like a family tradition to watch it while decorating, then it stopped streaming? Anyway to find it I searched “kid’s animation about a green slime man.” And now I’m here!
