Inexplicably, this cartoon short finds Mickey in the jungle. And, like most of the early Mickey cartoons, there is an absence of dialog and lots of music. While today this all seems pretty campy, it was state of the art in its day.
For the most part, there really isn't any plot--just lots of jungle creatures parading past the screen--singing and dancing like they are on stage. Then, you get to hear Mickey sing--and it's pretty sad--but fortunately he mostly avoids singing and plays various animals like musical instruments--and abusing them a bit in the process.
Far from a classic, there is still an odd charm about this. And, interestingly, Mickey once again plays (among other songs) "Turkey in the Straw"--the same tune he played in "Steamboat Willie" the year before--which was the first cartoon with sound.
