Rupert and Raggety Rupert : Season 1 Episode 9

Rupert's unsuccessful attempts to teach a cantankerous wood troll the meaning of friendship only causes problems for the Imps of Spring, hard pressed to bring spring to Nutwood on time. Only when Rupert allows their Wand of Spring to be destroyed in order to save the troll from his own mischief does the troll finally understand what being a friend is all about.
