Big Einsteins is the sequel to the preschool learning show Little Einsteins, but due to the team being all grown up, the show is for older audiences and comes on Disney XD, but it does reruns on Disney Junior, similar to The 7D.
The Little Einsteins are back, and their all grown up. And their going on new missions, new members to join, learning new music, a new Rocket, Rocketette, Rocket's girlfriend, new enemies, and... Same old Big Jet, except he's got a girlfriend too, Pink Sparrow.
