You have to give Disney props for the historical accuracy in Frozen though, it's clear that they obviously put a lot of effort into researching and contextualising the Scandinavian talking snowmen of the time. As a history student specialising in the talking snowmen of the Nordic states I'm so glad that Disney went the each mile and really shined a light onto them. Olaf is a extremely accurate depiction of the kind of talking snowmen which would have lived in that era.
