The three main characters in this made their debut in the short, I Haven't Got a Hat, as classmates in grade school, with Ham and Ex, the two dogs, singing the title tune. Animation being what it is, Beans is now their "Uncle" (despite the fact that they are dogs and Beans is a cat-that must lead to so entertaining family reunions). Beans is a firefighter and is called on to watch over the two pups, a duty he's given ample cause to regret accepting almost immediately.
There is very little that's as destructive as an animated child bent on mischief and Beans has charge of two at the same time. They get into almost everything-a helmet, a pair of boots, a fire hose-with rather predictable and at times funny results. They even trigger a false alarm which sends the station crew out on a run to fight a non-existent fire.
For this they are sent upstairs to take a nap, which is the last thing which interests them. They escalate their games until they actually drive a ladder truck through a station wall. Some nice sight gags highlight their ride and they eventually drive right back to the station, run up the stairs (in full sight of Beans) and pretend to be asleep. Beans buys the act and starts to leave when one throws a boot at him and they both start to sing and play, at which point he finally punishes them with a spanking.
Decent, though average. Worth seeing if you get the opportunity. Recommended.
