The title card this cartoon credits it to “Betty Boop and Bimbo”. I think that’s the first time we’ve seen Betty Boop’s last name established in one of these cartoons, and I’m surprised that doesn’t rate mention on the Wikipedia articles about this cartoon or about Talkartoons in general. This short also lacks animator credits. Talkartoon credits Shamus Culhane and Bernard Wolf, on what grounds I don’t know. Its release date was either the 9th of September, 1931, according to the Talkartoons page, or the 26th of September, according to its own page. Leonard Maltin’s Of Mice and Magic was the 26th, which makes for a neater arrangement of things altogether.
Most serieses grow stock templates for stories. It’s not laziness or anything exactly; it’s just that the people making a series realize they’ve got these characters who do this kind of thing well, and so go to telling that kind of story more. There is a loose template for Betty Boop and Bimbo cartoons: Betty wants to play with Bimbo, and they do, and some monster comes in and spoils the fun, often kidnapping Betty, until Bimbo rallies into action and everything collapses into chaos. Minding the Baby isn’t there. But I can see that template in embryo. Bimbo’s kid brother isn’t your classically-formed monster. But he does serve a lot of the same role, spoiling Betty and Bimbo’s fun and taking the initiative away from them.
We start with a crying baby and a gently wicked-in-that-30s-cartoon-way version of Rock-a-Bye-Baby. Bimbo’s got to watch his baby brother Aloysius. Also Bimbo has a baby brother Aloysius. This brings the ratio of Fictional People Named Aloysius To Show They’re The Comedy’s Annoying Character to Actual People Named Aloysius In Real Life to infinity-to-zero.
The cartoon’s a buffet of “Hey, that tune!” moments; right as Bimbo’s mother drops off Aloysius there’s background music burned into my brain as the tune for Betty Boop’s Birthday Party (“This is Betty’s/Birthday party jaaaaam”). There’s some incidental music around 2:00 that’s just in everything or at least feels like it. Similarly the jaunty little tune as Bimbo jumps rope. “Rock-a-Bye-Baby” and “How Dry I Am” and “By The Beautiful Sea” are cartoon staples, not just for this studio. The player piano-scroll music that the hippo plays with his snores has been driving me crazy because I can’t pin down the title. This whole paragraph is making me sound ill-prepared. The songs are there, though.
The cartoon’s got a story. It’s a loose one. Aloysius can go on making trouble, or at least old-baby jokes like smoking cigars and checking the Stuck Market, as long as it needs to. But there is reason for stuff to happen, and for Aloysius’s mischief to get bigger and bigger until it ends in some calamity. Surprising to me on rewatch was that Bimbo just gives up on watching Aloysius pretty early on. I’d expect good comic tension to be driven by his having to be both at Betty’s and keeping Aloysius from falling out the window. Instead, mostly, Aloysius gets into and out of his own trouble. Makes you wonder if they really need to watch the kid after all.
There’s no mice at all, suspiciously Mickey-like or otherwise. There’s a couple good bits of body horror. For me the biggest is the cat that gets pulled inside-out by the vacuum. I know there’s other people who’ll find more primal the punch line of Bimbo zipping Aloysius’s mouth closed. By the way, at the time zippers were a basically new thing. I mean, they had been invented decades earlier, but it was only in the 20s that design and manufacturing had got good enough that they could be used. To put the joke in a modern context it’d be kind of like synch’ing Aloysius’s voice to an iPhone that you then mute. I admit it’s a sloppy translation.
I’m not sure about a good blink-and-you-miss-it joke. There’s several nice bits of statues coming to life long enough to participate in the action. But they’re also pretty well-established. Bimbo dangling down a floor and licking a windowsill cake would be a good one, except it’s done a second time. Yes, in service of setting up a third dangle, where he licks a cat (to the same hilariously pathetic little “mew” as in Bimbo’s Express, I think). Still, the cartoon shows a good bit of polish. The setup’s reasonable, it’s developed well, and it comes to a conclusion that’s very nearly a full conclusion. The cartoons don’t feel slapdash at this point.
