I made this guy a few months ago, but kept forgetting to post him, haha.
Yes, he is a HE, but a SHINY male nidoran! Novel idea, huh? He is life sized, and I used some good ol' official artwork/sprites to get the sizing down.
I figured he looked better with pictures in a "natural" habitat, so no ruler is present. If you can find where I live though, you're more than welcome to use my hedges as a sizing reference
