It's time for the annual Friendly Falls Scavenger Hunt, which is mostly so that the town mayor doesn't have to do shopping once a year. Rusty McCabe is the favorite to win, but when Newton sees a rainbow, he thinks he'll find a pot of gold at the end. They do find the pot, but instead of gold, there's a universal remote that actually affects the universe, being able to pause time, make things go faster or slower, and so forth. Ned and Newton use it to thwart Rusty's victory, but each button only works once, so they need to get creative. They're about to win the scavenger hunt, when a group of leprechauns demand the remote back and hit the rewind button, rewinding the episode all the way back to the beginning.
