Belville and Scala are the shit, man. Rather un-Lego-like yet brilliant and sufficiently Lego-esque to be fun. Though admittedly the hands on Belville figures are small enough that they can and do get easily enough lost because they're truly ball-jointed, something that many major "action figure" manufacturers are yet to replicate as of 2022.
I also enjoy Fabuland, although growing up I had only random pieces of random Fabuland sets, never even a complete set. The figures looked so weird and I was sure they weren't even Lego, so imagine my surprise when I found Lego copyrights on them!> Clikits
I got some promo Clikits items back in the day, not sure honestly where. They're a very different type of building toy than what people usually think of when they think of Lego. Hard to say as I was never really the target audience, but I can say for sure that as an adult, the bracelets and shit are just too damn small and there's no way to work around that since they're molded single-piece chunks of plastic.> ZNAP
Not gonna lie, I first learned of this like a year or two ago. Kinda a bit too weird, even for my tastes.
