The Yodelling Dolphin of Kirkwall

King Arthur and Merlin set sail for Dolphin Rock in the Scottish waters near Kirkwall to collect Guinevere's latest desire - the Yodelling Dolphin. King Arthur's problems have only just begun when he discovers that hearing the Dolphin's yodel causes one to dance to death. Sneaking up on it underwater seems to be King Arthur's answer, but an octopus and a giant squid have other ideas.
