Swept Away Arthur, Buster and D.W. enjoy summer vacation at the beach. When it becomes unsafe to swim, Grandma Thora suggests building a sandcastle and they quickly become immersed in this pastime. When the tide threatens to sweep away their castle, Arthur isn't ready to let it go. Germophobia Buster friends are getting tired of his unclean habits --- he plays hide-and-seek in trash cans, eats food that's been on the ground and doesn't always wash his hands. They've decided he needs to clean up, or they're not coming to his pool party. When they teach him about germs, however, he begins to fear them everywhere. Now, he's afraid to touch anything and is seeing swarms of imaginary germs wherever he goes.
