Back in the chocolate factory, three of Charlie's grandparents refuse to leave their bed. Mr. Wonka gives them a rejuvenation formula called "Wonka-Vite". They take much more than they need, subtracting 80 years. Two become babies, but 78-year-old Grandma Georgina vanishes, having become "−2". Charlie and Mr. Wonka journey to "Minusland", where they track down Grandma Georgina's spirit. As she has no physical presence, Mr. Wonka sprays her with the opposite of "Wonka-Vite" - "Vita-Wonk" - in order to age her again. Mr. Wonka admits that it is not an accurate way to age a person, but the spray is the only way to dose "minuses". Upon leaving Minusland, they discover that Grandma Georgina is now 358 years old. Using cautious doses of Wonka-Vite and Vita-Wonk, the three grandparents are restored to their original ages.
