The kid’s mother who had the party booked for that afternoon call the shop to cancel it because her son has to study, the Bubigirls are feeling bad for the child because he spends his birthday studying so they decide to convince his mother to let him go to the party because they will make an educational party. The boy has a space exam so they organise a planetarium in the shop, with an antigravity station too where the Bubiloons will explain that part of the collection of themes. The kid, getting on a rocket, will travel around the different planets while the girls explain him in a fun way. At the end, as a prize because he remembers all, he goes into the space with the rocket to see the planets in live. The kid knows all of the themes and he has had a great time.
