Ok so, I was (re)watching Amphibia and I watched a scene (I forget what episode it was) and it had Andria's dad and Andrias before he became king. I was watching it, and I was like "Wait a second, that sounds like another character I know!" So I watched the scene multiple times to make sure, but Im pretty sure that the voice actor of young Andrias is the voice actor of Hunter from The Owl House!
