S2·E16 The Magnet Men, Part 4

After the 24th hour passes, the Magnet Men switches on their gravity gun which moves the Earth from its place and far from the sun. Not only do buildings and boats tip over, but water freezes and it starts snowing. Underdog and Polly realize that the reason why the gun attracted them were because of Underdog's metal ring and Polly's metal bracelet. Underdog flies back to the magnet planet without his ring and successfully fights the Magnet Men, destroying them and the gun. He manages to get the Earth back to its place in the sun and all's well that end's well.
