Mona is hesitant to play in the mud, but decides to dive in and embrace the messiness. After enjoying the mud, she takes a bubbly bath and learns that getting clean can be just as fun as getting messy! At lunch time, when Mona and Russell spill a bowl of blueberries all over the kitchen, Nana shows them how to clean up the mess. Mr. Wooka performs a puppet show about a town of clean freaks, and at the end of the day Nana reads a story about a very clean pig named Chloe.
