I decided to ask for opinions on this since the guidelines refer a lot to existing examples so it feels more like a "you know it when you see it once you're familiar" set of rules.
Basically the idea goes as follows:
Outfits following the style of a playboy_bunny outfit, but based on a specific pokémon. This can be either a human wearing a pokemon-themed outfit or a gijinka with an outfit of similar design.
There's search combinations that can find these, but no combination of two tags I'm aware of pick up most of these or these kinds of things exclusively.
Some examples:

In theory, a search of playboy_bunny_leotard and pokemon_(creature) would catch it, so the problem may be that such things are under-tagged, depending if the pokemon_(creature) tag is supposed to apply to cosplay or other things that reference a pokemon rather than having the actual pokemon present in the image.
