Okay, so you need to choose an imgflip age first. It does not have to be your age irl. Then you choose if you want to be shipped, adopt, or get adopted. You should make a bio in the mypersonalbio stream saying all of you imgflip information(gender, imgflip age, imgflip intrests, species, etc)
If you choose to be an animal, then you could join my family zoo! unfortunately, my husband and I have recently stopped adopting(we have a ton of kids) but I know some people in my fam that you could ask if you'd like!
