Pokeday
Pokeday was a day in TGChan (specifically January 16, 2010 EST) where /quest/ is flooded with different, mostly one-shot quests related to Pokemon. Whether this was a neatly organized collaboration between quest authors or just a bandwagon jumping is really unknown. Some of the games take place in the canon of PokémonQuest, others are stand-alone stories.
Here are the quests that appeared in Pokeday (this is in no particular order):
PQ Report - Follow Anna as she uncovers the mysteries of the underground works in the Pokemon World.
Krabby Quest - Krabby finds a way to be cool.
Rattata Quest - Rattata finds a way to express love. (Inspired by bg's Cutegal Quest)
Voltorb Quest - Voltorb does shit.
Shed a Tear - Shedinja was left alone by a novice trainer, and is on a search to find him again.
Pokemon Blue Version - Colbert finds himself in a very odd version of Pokemon Blue.
Pokemon Quest Gaiden - Clefable goes badass.
Meowth Quest - Meowth recruits Pokemon for a posse.
(Unnamed Pokemon Quest) - Dai Hoshiko aims to be the Pokemon Queen.
Pokequest - Harvey wants to be a Pokemon Trainer.
Some quests unrelated to Pokemon jumped into the bandwagon of Pokeday as well.
Cutebold Slaughter Fest - Triplilmus pulls out a creature that closely resembles an Oddish.
(Unnamed Quest - Possibly "101 Quest") - 101 plays some Pokemon.
