As a kid watching The Labyrinth, I always wondered what would have happened if Sarah had gone in for the cup of tea Mr. Worm offered her. I mean how would she have fit in his home!? Actually now that I think about it with my adult brain, maybe he didn't live in the rocks he was perched upon during this scene. Maybe he actually lived in a worm-sized mansion that would have easily or at least snuggly fit a human girl? Wherever his home, I wanted to go in and meet 'the Mrs.' so badly! I assumed she would have been polite but a little miffed at having unexpected company. She might not even have enough tea for a giant, bratty human!
I also wondered if the worm was being a dick in telling Sarah to go the wrong way or if he thought he was protecting her from going to the scary castle. Now, watching it with my adult brain, it seems pretty clear he was being valiant.
It seems strange to me, but there are a lot of people I know who never watched The Labyrinth as a kid. They claim they could never finish the movie because of David Bowie! Say what!? Clearly I need new friends.
