Random critters are a no-go. Other sellers take heed: “Mystery,” and “surprise” (random colored) listings cannot be accommodated and your listings may get taken down too. You need to photograph the exact item you’re selling. How this makes sense against made to order items that cannot be specifically photographed ahead of time, I have no idea.
Worry not my amazing friends and followers, the Squishpocalypse is coming. Your mystery critters and grab bags will not be gone for long.
