Having been inspired by the comments on this thread I quickly sketched out some characters which might work. The idea is to have something recognizable like the Lemmy lemming or Mastodon elephant which symbolizes the project.

At the core these are Kbeans, with the possibility of dressing them up as Kbeanauts/Kbinauts with the appropriate costume. These can be also be used like Reddit Snoos with a character creator where users can select facial features, hats, bins (baskets or boxes to sit in), props, and so forth.

I also tried sketching out some Koala mascots but it’s hard to make them identifiable when scaled to profile pic size. Figure wise they also don’t really fit well into a square frame unlike the beans.

BTW these mascots are made for the community. Please feel free to modify them, polish them up, and make your own variants. Developing a mascot should be a community effort.
