I went ahead and tried drawing again and I didn't have any numbness issues this time, yay! I had decided a bit ago that this specific Pokemon needed her character design, and the more I thought about her the more interesting I realized she was. Meet PallaPalla the Paras(ect).
When I was first going through Silver back in the day, when I was twelve, I named all my female Pokemon (with a few exceptions) in a repeating name pattern. I had been inspired by the Amazoness Quartet from Sailor Moon, which was airing at the time, and all of them have names like that. Hence, I had Pokemon with dumb names like BellaBella the Bellsprout, or whatever. 'PallaPalla' is actually the name of one of those Sailor Moon characters, so I have a clearer memory of her than some of the others. Even so, I never used that Paras or even thought about it really.
But then later on in the game, I encountered a shiny Paras in Mt. Moon! And I didn't catch it. I already had a Paras, I didn't need another. Mind you, I had at least a dozen Meowths in my Blue version so it's not like I had any problem with doubles. It doesn't help that Paras's shiny is near-identical to the regular colors, so I wasn't 100% sure I was looking at a shiny, even though I saw the sparkle go off. I was twelve, I give myself a pass for making a dumb decision. But I never forgot that wild shiny Paras, and the caught Paras that persuaded me not to catch the shiny.
Whenever I decide a new catch in a modern game (well...'modern' meaning anything from gen 3 and up) is the 'resurrection' of an old Pokemon (from gens 1 and 2), I give them little traits based on what I can remember. Thus, modern PallaPalla has design traits from her namesake AND a justification for non-standard colors. She's not shiny, but there's shininess somewhere in her memory data.
Designs like this are more about recovering and celebrating a memory more than anything. I put her down on (digital) paper and now she's real!
