So I was purchasing the La Leyenda films on iTunes so we can have better screenshots and I notied the description of Del Chupacabra refers to Alebrije and Teodora as Leo's imaginary friends. Now, admittedly I've only watched La Nahuala all the way through, and most of La Llorona so I can't be 100% certain if they pull a major twist reveal that his friends are actually in his hands or not, but it seems silly.
On a side note, I always thought the TV Guide synopsis for Steven Universe was pretty funny. It calls the Crystal Gems "Magical Space Outlaws" who "Protect the Universe from evil". I guess that fits?
