He is voiced by Ian James Corlett.
It's unknown how Hobie appeared in Gothel's manor. He is a friend of two another Gothel's captives: Rapunzel and Penelope. He always asks Rapunzel (and Penelope) to stay in the manor to not make Gothel angrier than she is. Though, when Rapunzel is out for too long, Hobie forces Penelope to go through the painting and remind Rapunzel about Gothel.
