Kobolds are lizards. Mythologically speaking kobolds were described as nearly everything BUT dogs. In original D&D they were like goblins before quickly being made lizardy. Ever since then they have been lizards. Why are Everquest kobolds dogs? This is literally unplayable.
All sirens clearly have hair, why do they so rarely drop it? Why do we all play a 20 year old elf sim? So many questions usually best not to think about them.
