Back when the show's craze was huge in 2011/2012, I wasn't 100% into it, but I decided to spring for one of those Funko Derpy figures. Figured it'd be a good way to keep people out of my house. The thinking went, "this stuff is so pervasive in society at this point, pretty much anyone will recognize this. It's the perfect human repellent." My plan was to tell unwelcome guests that I planned to collect more and see how they reacted.
Fast forward to today, I've gotten to know a few people in the fandom, invested myself somewhat in the show, and I've ended up collecting enough figures to fill a sizable shelf, so I guess the joke's on me.
But to answer the topic question directly, I used to watch the original Powerpuff Girls when it was still on the air, and this show's style always resonated that kind of vibe in me.
