Mock-up cartridge artwork for HYDRO-MANIA, appearing at a fraction of this size in Årkade (still crowdfunding over here: www.gofundme.com/arkadecomic )
Hydro-Mania was a video game I invented as a kid. It was a platform game a la Mario or Sonic except you played as anthropomorphic fire hydrants. There were four different hydrants, each with their own special ability: a tall one that could jump high, a tiny one that could squeeze into smaller areas, one with a pointy nose (?!) that could attack things with its nose, and I forget what the fourth one was because I lost the manual I created years ago. (and that's unusual, because I didn't lose very much old artwork over the years!)
As such, I also can't remember if I stole the concept of pipes from Mario.
...I probably did.
I went through a phase of being fascinated by fire hydrants because Rosetown had a fundraiser called "Adopt a Fire Hydrant Day" a few years prior where they had painted all their hydrants to look like different characters: football players, Ninja Turtles, and so on. I think there was one with Furrball from Tiny Toons Adventures on, which would place this event as occurring sometime around 1990. Much to my disappointment, they never did anything like this in my town.
TL;DR it's silly but I bet this is probably the most original concept I've ever come up with.
And I'm STILL sore that I lost the manual! I keep saying it was in a box that was thrown away because someone assumed it was recycling. My parents both deny this. Who knows!
