I liked this one a lot. Mostly because the style reminded me a lot of an episode of Courage the Cowardly Dog, a show that I am a fan of. I also like wacky and trippy scenes in shows, so this episode was kind of right up my alley. If you took Courage, Regular Show, and LSD (the video game for the PlayStation) and put them together, you'd get this episode. There were some things that I didn't like about this episode, like MoBros said, the episode does take awhile to actually get to Clarinetland, plus the episode scares me a bit, and I don't like getting scared.
