The short (like most of Tex Avery's theatrical cartoon work both on WB and when we worked at MGM) is a series of visual and verbal gags, usually based on outrageous stereotypes and plays on words, and topical references, is presented as a narrator (Gil Warren) describes a "tour" of the "Kalama Zoo" where the animals have nonsensical names, display anthropomorphic behavior, or illustrate punny gags. The only thing remotely related to a narrative is the running gag of Egghead (the prototype Elmer character) teasing a lion and paying for it in the end.
- Ax-Crazy: When asked by the narrator why he's acting loopy and crazy, the Rocky Mountain wildcat says this:"They called my name out at bank night, AND I WASN'T THERE!" (starts going crazy again)
- Bullying a Dragon: Egghead believes that taunting a hungry lion is a good idea.
- Bowdlerization: The scene of the camels smoking cigarettes was cut on TBS, Cartoon Network, and Boomerang.
- Hurricane of Puns: The cartoon crams as many animal puns as possible into 7 minutes.
- Informed Species: One monkey cage is labelled "Baboon", but the primate in it looks like a chimpanzee.
- Laser-Guided Karma: Egghead's constant teasing of the lion gets him eaten, despite the narrator warning him to stop.
- Pink Elephants: One exhibit shows floating pink elephants, a good two years before the Trope Namer comes out.
- Silly Animal Sound: The ostrich makes a chicken-like cluck after laying an egg.
- Suddenly SHOUTING!: "HEY SISTER! CAN'T YA READ?!" shouts a monkey after an old woman tries feeding him some peanuts, the latter ignoring a "Don't Feed The Animals" sign. He even shows her the sign as a bonus.
- Too Dumb to Live: Egghead continues teasing the lion even though the narrator tells him to stop, he eventually gets eaten.
