Well, I don't have any adoptables, but I have drawn a pencil sketch of every species of Neopet. If you'd like, you may use the image and color it and put it on your petpage or whatever, just give me credit. According to Neo's rules, you may not use these images for the Beauty Contest or Art Gallery.

All the pets are in a single jpeg image, so if you right click and choose Save As, you'll be saving all 54 of them. If you want just one pet, you'd be better off taking a screencap, I think.
