As Bob gets to work building a new one, Roley thinks that Muck blames him for the disaster. Muck loves to get mucky, so she's horrified to lean that Bob is building a machine wash to get them all clean! Mucky Muck becomes determined to get muckier than ever before. Eventually, she can resist the machine was no longer and is surprised to find how much fun the ticklish machine wash is!
