It is a happy day for everyone when Grandma Joyce decides to take nine of her grandchildren to the park for a picnic.

As Grandma Joyce packs up the picnic basket with sandwiches, juice boxes, and her special cookies, everyone is so excited! But little do they know that they are about to have a memorable and mysterious adventure like no other. After they eat their lunch under a big, beautiful tree, some of the grandchildren go to the playground while Grandma Joyce takes Khloe on a walk. But after they come upon a row of bushes that suddenly move, Grandma Joyce and Khloe stumble upon a spectacular secret passageway that leads to a mountain made of gumdrops!

After Grandma Joyce gathers the rest of the grandkids and Grandpa Johnny, they all embark on a magical adventure where rocks are made of bubble gum, swing sets are made of candy sticks, and little gingerbread men welcome them. Gumdrop Mountain is the delightful children's tale of a grandmother, grandfather, and their beloved grandchildren as they enjoy a fun day in a yummy land where everything is made of candy and cookies.
