I feel I should post this here. This is King Purple Bunny in his crown (has since been slightly upgraded to one very similar but with more jewels), royal coat, medal, trophy, sceptre and royal carrot (has also been upgraded to a gold one). I'm fairly sure he's sitting on a throne but you can't see it.
He has an account on the Fediverse at @[email protected] but doesn't post much (the bunny in charge of it thinks it's too much admin, unless he is also able to post about himself).
That's lovely, I'm glad they've got to spend all that time with you!
