There are a number of special occurences in Corruption of Champions which are programmed to only trigger when the dating system of a player's computer is set to a specific date.

  • Bunny Girl: Originally intended to only appear on Easter (March 31), she is unique in that she is the only Yearly Event NPC to instead be encountered all year around, and she can thusly be found in the Plains. She possibly has slightly different scenes when the date is Easter, though.
  • Cockgobbler: A harpy mutant who appears to PCs on Thanksgiving (November 22).
  • Fera: A rogue goddess who can be encountered in the Deepwoods on Halloween (October 31).
  • My Little Pony XOver: A joke encounter that can only be found on April Fool's Day (April 1), but only by Centaur characters who go to the Lake. The result is an encounter with the main characters (or "Mane Six", in fandom lingo) of the TV series "My Little Pony: Friendship is Magic", which causes a strange "ponyfication" of the player's horse-body that effectively redesigns it to resemble the art style of the show.
  • Piggy Slut: A masochistic, submissive, honey-lactating and jizzing pig-girl whore who can be rented for a gem at the Wet Bitch on Thanksgiving.
  • X-mas Elf: A female elf who approaches the player on Christmas (December 25).
  • Easter 2013 saw no less than four special events, including one to be continued as a rare event (March 31 2013):
    • Egg drops: Easter day 2013 all monsters have a chance of dropping an egg of some kind when beaten.
    • Bunny Girl transformation: Having 69 sex with the Bunny Girl on Easter day 2013 causes the character to immediately grow bunny ears and tail. (March 31 2013).
    • Restrained bunny girl: Aspecial encounter with the bunny-girl where she’s been restrained and fucked completely full of eggs, with options as to how to deal with her depending on gender. This one will still be around after Easter, though it will be much more rare. The scene was penned by Adjatha.
    • Chocolate massage: Joey offers a special - and rather messy - chocolate massage for 20 gems.

  • Carol: around Christmas (assumable December 25 - 31) if you explore the High Mountain, you may encounter a godess-like figure, granting access to a miniquest to search for the key in the Mountain to revive a knight named North.
