Grampa Was an Alien

Lewis goes on vacation with his family - minus his beloved "Grampy" and his stories. However, Lewis has found Grampa's journal, which mom, Janet believes to be fairy tales written by her dad. On their vacation she reads to Lewis every night out of Grampa's book, about a little boy named "E-fan", who lives with alien parents on another planet, and who goes on vacation to a moon - one of Gizmok's 7 moons. Fancy that! Mom and Pops also begin reading a story for themselves, that she had never heard from her father while growing up ... and she's capitvated by it.
