>>93916987Combining tools was a pretty popular gimmicky trend through a lot of the 20th century. Like having a swiss army knife that had your knife, can opener, and screwdriver folded up right in your pocket was a nifty and novel idea when it first came out. A lot of people made products trying to capitalize on the novelty of that concept. And by the 80s and 90s it was a popular joke to parody that trend and have a would-be inventor character just slap together appliances or tools that really probably shouldn't go together resulting in a shoddy nonsensical product that no one would actually buy. I think they did the same basic joke in the Gremlins and probably in Honey I Shrunk the Kids. But in Brave Little Toaster it's obviously taken a step further by having the appliances be sentient, meaning the mishmash would be like a frankenstein's monster.
As for screwing the forks onto the kettle, I'm sure that was just to make the design look zany, there was probably no idea of a purpose behind it.
