Tilly is dressed as her alter-ego, SuperTilly – the greatest superhero in the universe!  When her dad asks her if she can send him his toolbox, it’s SuperTilly to the rescue! Tilly accidentally sends the tool box to the wrong moon, and refuses Ella’s help.  Ella follows her to Titan where they find the now empty tool box. Slippy and Madhu arrive to help but Tilly once again refuses. Tilly realizes that sometimes superheroes need super sidekicks (and a super-sister!) to get the job done.

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!
