Before Pluto, Mickey was paired up with a large elephant serving as his exotic hunting "dog". The cartoon begins with the two out in the jungle searching for game while playing a few merry tunes on an accordion.
Unfortunately for hunter Mickey, he stumbles across an unfriendly bear and a ferocious lion. Teeth bared, the hungry animals scare Mickey out of his wits!
It's a habit of Mickey's to use nearby animals as musical instruments, and he does not fail to amuse here. Whether it's using tiger whiskers as a harp, tiger screams for melody, or a lion's tongue for an instrumental plucking, Mickey certainly is creative.
My favorite gag in this toon is the lion who does the hula. He uses his mane as a skirt and a nearby snake as an inventive lei.
All in all Jungle Rhythm does not present anything notable storywise, but its gags make it one of the better films in Mickey's early career.
