He is optimistic, intelligent, quirky, cheerful, kind, nice, jolly, funny, silly, friendly, upbeat, energetic, playful, smart, sweet, and helpful. And like Steve, he could give out wrong answers during thinking time but is delighted when the viewers help him along the way. He is the first host to wink more than one time in every single episode of Blue’s Clues & You. Mostly, he winks at the viewers. He also smiles all the time, as revealed in the episode Playdate with Magenta.
Josh has tan skin, brown eyes, and dark brown hair. He wears a striped shirt, just like Steve's but it's blue instead of green and without a collar. He also wears jeans and blue sneakers with red laces.
Josh made his first appearance in the premiere episode of Blue's Clues & You! (Meet Josh!). Before the reboot's debut, Josh was featured in a promotional photo and a teaser trailer.
