Nokk

Nokk is one of the spirits in the enchanted forest. He is the water spirit. He attacked Elsa once when she was trying to get across the Dark Sea. After Elsa put a rein on him, he helpfully crossed her across the Dark sea to Ahtohalan. Elsa started singing Show Yourself while she was riding with Nokk to Ahtohalan. At the end of frozen II, Elsa freezes Nokk so he can ride on solid ground.
