These are a pair of humanoid siblings, Ralph Nicky Barrison (RNB) and Paige Nicola Barrison (PNB). RNB is basically the Tails to BEC's Sonic and is his best humanoid friend. PNB on the other hand, is a kindhearted yet naive ditz, somewhat like Leni Loud. Nevertheless, these heterochromia siblings have each others' backs through and through, along with being MASSIVE chocolate addicts.
