Library

Library is the third episode of Season Two.

Summary
It starts with Nina at the library, expressing her love for story time. The librarian begins to read a story about a brave knight, who sailed across a giant sea, rowed across a great lake, and waded across a big river to battle a dragon, but the water gave the knight a problem. Nina then interrupts the story saying she needs to pee. A toddler boy points towards the bathroom on request, and Nina walks through shelves of books past Kate and Frank. Frank follows Nina. She asks for directions, but everyone shushes her and someone gets a drink. Nana then appears, and everyone shushes her, but she apologizes and declares it a bathroom emergency. They ride on a cart while sorting books. One, about waterfalls, scares Nina, and they end up on lights, which they jump on to get to the bathroom. A little girl, who is drawing, is impressed. Nina pees in the bathroom. They then go back how they came to avoid missing the end of the story. The librarian is finishing the story, at a part about going to the bathroom, and then Nina interrupts the knight's dialogue with her catchphrase: "That will never happen again because now I know, don't wait to go."
