Proposal for Mastodon: Trunky.

It's bouncy and fun sounding with bright percussive phonemes. The "R" also gives it an energetic vibe.

Being a microblogging platform, it can both be a reference of how one truncates one's messages, but also maintain the mammoth reference as well as sidelong imply the other definitions of 'trunk' which are also useful: a box where you keep stuff, and the central pathway from which other pathways branch.

You can keep calling the posts "toots" too.

However, I think "Favorites" should just be called Likes, or hell ... updoots if you REALLY want to lean into the mascot.

If so, however, boosting and bookmarking should also be changed to align with the mascot.

Either call them Retoots ... or Trumpets! And bookmarking can just be called "Remember" (because "Elephants Never Forget")
