You know how sometimes birds groom rhinos by pecking bugs and such off of them? If Nidorino was real and in the African plains somewhere, he couldn't get such treatment, being all lethal-poisonous. "Lemme just get this tick off your bac--OOPS I'm dead."
You realize this is the first time I've drawn a generic Nidorino to put in the corresponding gallery? Furthermore, to counteract my bunny-rinos, I've made this one to take after the rhino side a lot more closely. Colored with digital pastels throughout.
