Funky Forest: The First Contact

A collection of Japanese vignettes with seemingly little in common, but there's a plot there somewhere. There are three girls who make the acquaintance of a 39 year old guy and they have some fun with him, playing pingpong and going on picnics and such. Then there are a couple of weird dream sequences. Then "the guitar brothers" (one of whom is the 39 year old guy) listen to the middle brother play guitar and sing. There's some really messed up animation in here as well. Not really sure what to make of it (I've had this problem before with Japanese movies…)
