In GoldieBlox and the Dunk Tank, Goldie has to find a way to get Nacho clean. The only problem is: Nacho hates water and loves being a dirty dog. After many tries to get Nacho clean, Goldie finally comes up with the perfect contraption. As kids read along, they help Goldie build a dunk tank (and learn about hinges and levers) to get Nacho clean so everyone can go to the carnival on time.
