Interstellar Ella

The gang is practicing to play Saturn Dance with Priya when she calls to tell them she is sick. She won't be able to come. Ella is very disappointed and wonders how they can cheer up Priya.

Ella has her best idea yet for a fun day. They will visit a nebula for each member of the family! Up first is Bernard 68, but it is very dark and frightens Tilly. When Dad's truck breaks down, they head to the Boomerang nebula.

Ella is excited to get her own room but Tilly is not as thrilled. She asks Slippy if he can make her a time machine to slow down time so tomorrow never comes. Slippy says the only place time shows down is around black holes.

Slippy needs iron to fix his spaceracer. Ella tows him to a metal asteroid where Glitch is instructed to cut off a small piece. But when Ella distracts him, he accidentally cuts the asteroid into two large pieces! Ella feels responsible

Ella stretches the truth a bit when she tells Angelie she can comet surf. She decides to try but finds it's a lot harder than it looks. Slippy adds rockets to an asteroid so Ella can practice on that instead.

It's Priya's birthday, so the gang is looking for something special as a gift for her. Ella suggests a birthday star, which is a star that is the same light years away as your age.

When Glitch’s compartment empties out and a huge amount of junk floats out, Ella suggests that Slippy get rid of it.

Ella finds her Nanny's old Hide and Peek device and hopes to beat Slippy's record for Hide and Seek! Gem and I.Lo are playing too. Slippy decides to make things more interesting by siphoning fuel from the Hide and Peek.

When Angelie breaks Slippy's Jupiter gliding record, he's equally upset and fascinated by her surfboard. The two agree on a rematch and set out to work on their vehicles. They both ask Ella for help.

Ella, Tilly, Slippy and Madhu are playing a game on the moon when it starts to rumble. The ground cracks open, and they fall into what they discover is a large network of tunnels underground.
