Bean and Cosa are thrilled to discover that Kami's mom is an explorer who travels the whole world making maps. After misinterpreting a dream about the sea, Bean decides to encourage Kami to be an explorer just like her mom. That makes the shy origami sad, since she doesn't want to be pressured to venture outdoors. To make up for being insensitive to his friend, Bean must now find a way to bring the adventure to Kami, without her having to leave the house. Will our bean sprout be able to bring the entire ocean into the Library?
