The shopkeeper at Wandering Oaken's Trading Post is Oaken.
Oaken appears in Frozen as the cheerful owner of Wandering Oaken's Trading Post and Sauna, a remote business in the snowy wilderness near Arendelle. Anna visits his shop while searching for supplies and winter clothing after Elsa's powers plunge the kingdom into an endless winter.
The character is memorable for his booming greeting, “Yoo-hoo!” and his sudden shift from friendly salesman to intimidating giant when Anna's party causes trouble. He is also the voice of the famous “big summer blowout” sales pitch. Oaken is voiced by Chris Williams, who later co-directed Big Hero 6 and Moana.
A common mix-up is confusing Oaken with Kristoff. Kristoff is an ice harvester and Anna's companion, while Oaken owns the trading post. Pabbie is the leader of the trolls, and Hans is Anna's former fiancé.
