When Ella heads out to collect space materials for the Clubhouse, she borrows Slippy’s luckiest good luck charm, Mooncake. Mooncake proves to be very lucky indeed as Ella finds everything on the list, even a sofa! But when Ella arrives at a black hole, Mooncake is bumped into its strong gravity. Ella knows Slippy will be sad to lose Mooncake. She can’t let that happen so calls her for help. It’s only when everyone pools their strengths that Mooncake is returned to Slippy, safe and sound.

The year is 3021. The place is the Milky Way, where eight-year-old Ella gleefully heads out with her friends on exciting adventures of discovery. At only eight, she already knows quite a bit about space... but there is always more to explore!
