Nidorino, like its previous evolution is quite close in form and shape to a rabbit. but unlike its past form, it leans a lot closer to rhino with a change in its snout, prominent horn, and overall body shape. The bristling of its spines could also be a reference to porcupines and hedgehogs.

As mentioned previously with its counterpart, Nidorino's shiny coloring closely resembles the blues in Nidorina's base palette. The light blue skin with darker blue spots match perfectly. It's inner ear, however, remains a dull orange similar to Nidoran♂'s shiny.
