Carney, a young fox working as a royal courier, is one of two main protagonists in Delivery!. Although I have no exact preference for accent besides maybe something a little more country-esque, he should sound youthful and boisterous; if you gave maple syrup sentience and slapped it on a canine, you'd get Carney. As Carney's something of a glass-half-full type of guy, be able to convey a lot of enthusiasm in your voice!
