A mysterious alien entity lands in Smileyland. Kaeloo and Quack Quack like it, but Mr. Cat and Stumpy want to get rid of it.
"Let's Play the Thing from Outer Space" contains the following tropes:
- Came from the Sky: The episode is about the main four finding an object from space which fell out of the sky.
- Does This Remind You of Anything?: The argument the main four have about keeping the titular thing from outer space in Smileyland or launching it back into space sounds like people arguing about deporting immigrants from their country.
