Gram Hatter and Kat set off on an adventure. Gram quickly folds up a pirate hat and places it on Kat's head, and they begin their mission to help clean up the city park. Volunteering turns into a treasure hunt as Kat finds pennies, nickels, dimes, quarters, and even a dollar. With each discovery, Kat gets a new hat, and Gram Hatter teaches Kat how to count her coins as they pick up litter at the park. When Kat adds up her money, there's enough for ice cream. Or should she donate the money to support the park instead?
