On a travel tip from Ray Bradbury, Bugs ends up in King Arthur's time and is mistaken for a "dwagon" by the always astute Sir Elmer of Fudde.

Bugs Bunny is trying to reach a peanut festival in Georgia, but he has instead time traveled to Camelot in the year 526. He blames faulty directions from Ray Bradbury, and mentions having previously time traveled to 25th-century Mars thanks to Bradbury. Bugs at first thinks that he has landed in Pittsburgh, but is informed that he is in Camelot by Sir Elmer of Fudde, a brave knight. The knight has been hunting for a dragon, and figures that Bugs is a transformed dragon. He captures Bugs and takes him to the castle of king Arthur, where Bugs is presented to Arthur, King of England (played by Daffy Duck), and court magician Merlin of Monroe (played by Yosemite Sam). Merlin wants Bugs drawn and quartered, but Bugs uses a solar eclipse to fool the locals that he can affect the sun's movements. He is released and Arthur grants him custody of an actual fire-breathing dragon. Bugs establishes his own armor-making factory, and names it Acme. In 528, his enemy Elmer challenges to a duel, and Merlin has allied with Elmer. Bugs much achieve victory to secure his position in Camelot.—Dimos I
