As often happens in cases like this, where I try to cook up a number of little pieces in rapid succession, I find myself revisiting old friends--in addition to the usual multi-purpose mice, there's a Battle Hamster diva, and the one in progress is one of our old buddies, the Happy Trolls. (I have a terrible soft spot for the happy trolls.) Eventually, I'm sure a pink lizard and a slug will make an appearance, or maybe one of the Snocketbeasts. I haven't noticed any particular sales spike for recurring characters--the pink lizards do pretty well, but I haven't heard from anybody actively collecting any particular type of character--but contemplating it does make me realize how many weird little critters populate my brain. I never think of them in terms of "This Is My Character" the way that you see it in fandoms--when I think of a character of mine, I think Digger, or Ed, or Chu, or whoever. Or, to a much lesser extent, Eland the antelope, and the Donkey and Goldfish. Creatures like the mouse-tailed gnomes and the Battle Hamsters and the happy trolls, though, who aren't really recurrent individuals, are more like...I dunno. They fall somewhere between a sort of personal symbolic vocabulary* and on-site field studies of purely mental wildlife.
Which is way too much thinking about a happy troll, so I'm gonna go get lunch before my sinking blood sugar leads me to write the Trolls In Art Manifesto or something equally absurd.
*This is way too big a phrase to apply to a neurotic pink lizard with a straight face.
