there are toys alredy. such as my example of a cupcake-turtle. i don't recall exactly. but some kid's pay to use, closed species adoptable was a turtle+food. found a toy just like it, posted with "so you going to go after them?"
pet+snack sounds cute, but as a "this is species of fox is also part icecream, nobody knows how the biology works" gets dumb, or weird. then of course, there is the idea that we should have edible pets. if worst comes to frutition, you're going to need to eat your best bud.
I wanted in on it. one thing these adoptables closed species needs is lore. I forgot what my Avivittles had. they have gems that make them sentient, or "part food". bird races are rare in the adopts community, and more rare when "it's also food"
so, the one and only Avivittle, made by me.
