Petunia! She's the companion/mount of my orc oc Halcyon (whom I'll eventually share)!

The world she is from (Hoivata, my retired dnd setting) was fucked by a giant magical event. It caused animals and plants to mix and mash with prehistoric and fantasy creatures. She is a cera, which is basically a mix of triceratops/styracosaurus, moles, and porcupines!

They vary GREATLY in appearance between seasons due to the harsh environment they live in. Her spring/summer form looks nothing alike! Fall and Winter are mating season for ceras, so she gets super bright in color! It also helps scare away large predators/threats!
