Helga and her friends dress up as aliens in 'Hey Arnold'
10 Kids’ TV Shows With Episodes About Aliens, Because They’re Having A Moment

The truth is out there!

Aliens are having a moment right now — it happens every few years, in our experience — and whether or not you believe in life beyond our little blue and green marble you have to admit that the thought is pretty fun. You know who else thinks so? Children’s shows. So we’ve rounded up some of our very favorite kids’ show episodes about aliens, from classic shows from the ’90s to fresh new series.

Alien episodes of children’s shows tend to fall into one of two categories: whimsical good fun or skeptical cautionary tales. More often than not, an “alien episode,” usually turns out to be a much ado about nothing situation, where characters imaginations get the better of them and everyone learns to be more discerning about where they’re getting their information. (Honestly, it feels like a particularly relevant lesson to teach kids in the modern media landscape, aliens or no aliens.) But in other episodes, the aliens present either an exciting, silly break from reality or a spooky look into worlds beyond our own. Whatever the vibe, alien episodes, especially in kids shows, are just a delightful romp.

Enjoy these out of this world episodes as a family. (Come on: you knew we had to do it...)
