If you have a good picture (own, friend's, found online) that fits this account you can contribute!
DM the picture to this account (it removes the handle), add a source, the species and an image description and after being approved by the mod your toot will be added to the queue.
It should look something like this (emojis and fun fact optional)
Bears! in the loosest definition of the word. All arctoidea welcome. Maybe even koalas.
BEARDS! BREADS! BEARS?
