I could picture Slugcat parts being pieces in the character editor. They have a similar-enough anatomy to Guardian Spirits, I wager. Just need a thicker tail.
Which is why it would be nice to get some more options for both males and females.
Other ideas include a dolphin spirit with cetacean genitalia and a shark spirit with claspers, both for the lake, a reptile spirit with hemipenes, and a bird spirit with a cloaca.
