For anyone curious, still not announced, host of the jam seems to be temporarily unavailable.
In the Discord, the below were announced to be the planned wildcards, and appear to be the *official* list of wildcards as discussed with the jam host. Putting it here for any non-Discord users in this jam <3
..but the last one is 10/10 a meme and probably not "official", even if it's still optional xD
Use or do not use the WILLOWCARD at your own peril ;)
