BUR #17622 has been approved by @nonamethanks.
rename pikmin -> pikmin_1
create implication olimin -> olimar
create alias pikmar -> olimin
I know I'm probably the only person doing much for pikmin (series) here right now, but I would like to make these small requests. pikmin as it currently stands is an utterly obnoxious tag, as most artists who use it are actually referring to pikmin (series) or the titular creatures of the games (but I made character tags for those), and not Pikmin as in the first game. If that were the case, they would tag it with Pikmin 1. As it currently stands, it makes the tag show up in the autotags with its series tag, even for images obviously not associated with the first game. So I feel it would be better to just rename it to Pikmin 1, since while game title inaccurate, it does make for much easier sorting since that way you won't get unrelated images accidentally ending up in what should be the copyright tag for the first game.
As for olimin, it's literally for versions of olimar post bad ending of the first game. It's a small tag right now (as in only one image tagged right now, though I do know post #2440468 is a parody of Pikmin 1's bad ending with Touhou characters, so I don't know), but I'm expecting this tag is going to be needed as I have no trouble finding artwork with that tag (as well as just being useful to have around). Olimin (and Pikmar) are admittedly fan nicknames for this alternate version of Olimar, so having them outright renamed if need be is always an option for it. But since I feel they work and communicate their purpose pretty well at the moment, I'd just alias Pikmar to Olimin (the more common of the two nicknames) and naturally imply it to Olimar.
Anyway, this is insanely lengthy for a bulk update request reason, but pikmin (series) is definitely on the nicher side of things here on Danbooru, so I hope you will consider my requests.
