As a challenge I tried to assemble the original 15 Pongo/Perdita pups and try to make them distinct. This was harder than I thought. Plus adopted pups like Tripod and Princess are not included for obvious reasons.
Fidget, Ink-Blot (I know this was a Lucky design for merch, but we know that’s NOT Lucky!) Wizzer, Dipstick, Freckles, Cadpig, Rolly, Lucky, Pawprint, Patch, Jewel, Two-Tone, Missy, Penny, and Pepper.
