Monster Falls has captured my heart and run away with it. Have some Deer!Dippers.
Also I should note because I am a biology nerd: Deer!Dip would probably be based off of mule deer colors/antlers, if he was ever a deer long enough to have full-grown antlers. No White-tails live in CA/OR, but Mule deer are abundant.
Also, fun fact: Mule deer “stot” to show off fitness or prowess or to just show off to a predator that they’re to weak to catch them. I like to think that Deer!Dipper probably enjoys stotting a lot once he grows accustomed to it and sees that being half-deer is pretty badass actually.
