I have players that were orc, kobold, Half Celestial, Aasimar, Tiefling, lizardman, nixie, pixie, troll, giant, thi kreen, a spellcasting frog and others.
Including a human mage that was reincarnated as a badger and continued with that character.
When you talk about polymorphs and strange magic effects we had a winged feebleminded dog, and a miniature bald purple caribou.
