It’s my headcannon that they eventually make it back home, but we’ll never know because the series ended with them attempting to escape.

A Headcannon is a story (or really anything) that is added on to or changed in a persons mind. For example, in Undertale, someone may make up a story on how Papyrus joined the Royal guard, since this doesn't happen in-game, this makes it someone's headcannon. Headcannons usually aren't shared, but you can find headcannons of many things on many different social platforms.

A miniature cannon mounted on one’s head. Used mainly to prank unsuspecting friends. A headcannon is very difficult to ignore.
