Before Neopets were converted into customisable creatures, there was nothing but static GIF images that served as your pixelated companion. Since the pet poses were not constrained by a rigid structure to align with other clothing, a good number of Neopets had unique poses, similar to how Mutant, Baby, Maraquan, and Veggie pets have a unique body pose today. When the big conversion happened, TNT allowed for some pets to stay in their pre-customisation poses, at the expense of not being able to dress them up.
Below, you'll find a list of those pets that are able to remain in their "unconverted" state (if their owners wanted them to remain so). Click on each pet to see a big, blown up SWF version of pet you would see today on pet lookups. (The SWFs are great for designing lookups and layouts!)
