They return home once in "Welcome" only to run back in their spaceship and crash on Earth again because an angry mob of humans meets them on Zigma B.
It wasn't even the series finale
The series has been airing from 1997 to 2008 and still no conclusion
The characters could have simply given the humans their ship so the humans can go back home and the goofs can stay on their home planet but it's a dumb show for kids so fuck common sense
Stereo only appears twice in season 2 and not in that episode when he could have helped
Sorry but I binge-watched the show on YouTube and it was weird seeing a show from my childhood again. Still disappointed.
Disappointing revisits to old shows general?
