Crystal is kind and charismatic, taking on the persona of a 1960s hippie by starting sentences with the word "like" and using "groovy." As a dog, Amber is a bit more mature than most canines, but dep down is a kind and protective pooch. Though they may look like a beautiful human photographer and her Golden Retriever, both Crystal and Amber are alien government agents using a peace sign necklace as a means to create an artificial disguise, keeping their true selves a secret from humans.
