Elinor and her friends want to bring Ms. Mole a cupcake for her birthday, but they're worried it will get squished on the way to school. The kids find inspiration in nature when they observe how different animals/creatures stay safe using their shells as a defense mechanism. Elinor, Ari and Olive use this idea as inspiration to make a shell around the cupcake using a hard coconut. Because of the kids' hard work and ingenuity, the cupcake makes it all the way to school without being squished, just in time for Ms. Mole to enjoy her present. Yum!
