yesterday one of my pet rats named "Maple" died, one of the sweetest rats ever, I think there should be an easter egg to remember her.
if you don't want to I understand.
i have made a texture:

and here is Maple

Rip Maple

I never check issues, sorry I missed this. I'm late now, but I'm sorry for your loss. However, I don't think I can add other people's pets cause more people will then ask and it'll get out of hand. You could make an addon to have that feature if you wanted.
