Beaches Are Like Deserts I

ROOMBA is going to the beach with Jill tomorrow. When Jill invited ROOMBA, she mentioned that she would like to build a sandcastle during their visit. Unfortunately, ROOMBA has no information on building sandcastles. Based on the data and experience ROOMBA has for castles, ROOMBA expects this to be a major undertaking. Since ROOMBA cannot provide expertise and guidance for the sandcastle architecture and construction, ROOMBA would like to be prepared to provide tools and labor. Will you help ROOMBA find the right tools for the job? (Hint: The items requested are in Rosalie's Beach Tote which is available in the June Starter pack or by completing 28 days of chores)
