Part of the long running 'Minna no Uta' program on NHK, which are two-minute long animated music videos. Meaning "Songs for Everyone", this has been a staple of the network for almost six decades, and usually the all-audiences songs are aimed at the younger viewers. Covering all types of songs and all types of animation styles, generally not very sophisticated artwork or animation, and not long enough to tell a real story. Just a couple minutes to fill in the broadcast until the next show.
Everybody calypso! To the strange garbage monster growing on the edge of town! Basically, this is nothing more than a cautionary tale to children to "don't pollute". Colorful fingerpaint style artwork aimed at a younger audience.
