It is first seen when Sandy pumps it on Earth. SpongeBob asks if it is a tool for "alien hunting," but Sandy says that it is used to collect samples, such as rocks, that appear on the moon.
When SpongeBob and Patrick
"arrive" at the "moon," they use it to hunt "aliens," who are really the Bikini Bottomites
