Nature Calls, Part 1.On the way to Nature Civilization Land, Shobu realizes that his father's Deck Case is very unusual—especially since it drove away angry monsters. Anyway, the gang meets a young girl named Flora, who's willing to take Shobu to the mystical Treedom, which is a long-lost giant robot covered in moss. After all, who needs freaky magical powers to make cards come alive when you have a giant robot that can blow things up at a rate of 300 epms (explosions-per-minute)? But Princess Pollyanna of Green Gables wants the Treedom for P.L.O.O.P., and not even Shobu's gonna stand in her way!
