Disney’s Little Einsteins S1 E24: A Galactic Goodnight (UK Dub)

The team are having a sleepover in the Rocket Room at nightfall. They all have special tricks to fall asleep, except Rocket. He has trouble falling asleep. Even the gang’s own attempts to make Rocket sleep fail, the only way he can fall asleep is to go to outer space and count eight planets and one dwarf planet (making it nine planets in total), thanks to his planet mobile for showing it.
