 The episode was written by John Swartzwelder and directed by Mark <unk> . The idea for the episode was pitched by the Simpsons writing staff , who wanted to make an episode in which Mr. Burns becomes a " <unk> " , a millionaire who goes on thrilling adventures . Although it would originally be green , a mistake in the overseas animation led to the Loch Ness monster looking pink , a mistake that was ultimately too expensive to fix .
