The Magical Flying Library Ship is a library on a ship, owned by Brother Otogitchi and Sister Otogitchi. It visits Tamagotchi School in Tamagotchi: Happiest Story in the Universe! and has all the books can take Tamagotchis on adventures inside the stories.
To enter any of the books in the library, the reader has to recite a magic incantation: "Picture book, pui pui, here I come!", and make a side-to-side motion when they say "pui pui".
