The answer to that question is, of course, no!
Just for fun, I took this photo of my current collection of "Chinasaurs," or Hong Kong dino-monsters, or whatever else you want to call them considering they don't have an official name. What I love about these things is that because they've been around for decades and have been reproduced and knocked off so many times, there's a pretty much endless amount of variations out there to collect.
In this photo alone, there's the standard hard plastic (badly) painted ones, smaller variations of them, hard plastic monochromatic ones, soft rubber translucent capsule machine and arcade bootlegs, and even an eraser (the solid green guy in the middle).
I have been adding to this collection since I was a very young kid, and I'm sure I'll continue to do so for years to come.
What about you? Do you collect these? How many different variations have you been able to find?
