"Meet Astrid and Stella! These best friends are ready to fire up the turbo pumps and blast off into the stratosphere! In their first adventure, they will discover the cute-and-cuddly planet Caturn and beach-covered planet Bloop. At each stop, they'll meet new pals, solve friendship conundrums, and stop one evil tyrant -- with lots of dance breaks and snack attacks along the way" -- Adapted from back cover.
