The Region of Ice

When on a skiing holiday in the icy regions of Eternia, the Royal Family are captured by an Ice Lord. Orko scares the Ice Lord by pretending he is He-Man (!), and the Ice Lord explains that Skeletor has kidnapped his daughter and will only release her if the Ice Lord delivers the Royal Family to him. Orko convinces the Ice Lord to free Prince Adam (who he calls his 'assistant'), then Adam becomes He-Man and sets off to Snake Mountain with Orko to rescue the Ice Lord's daughter.
