Charlie and Lola

But We Always Do It Like This (3x9)

:

When Charlie and Lola go to the beach by their grandparents' house, they begin their tradition of building a sand castle. However, a girl named Clem becomes curious about the summer's castle. Clem examines Lola's shells, takes Lola's spade, erratically places seashells on the castle, and accidentally falls on the castle.
