So anyone familiar with the opening credits of Goonies will remember that it introduces all the characters by showing them as they are going about their daily activities, meanwhile the Fratelli's are being chased by the police in the background.
The whole scene can be seen here, however I've set the link to start at the 3 minute mark where we see the character Stef who appears to be on the docks, with her head in a giant trough(?) under water, and she comes up with a crab which she then tosses aside. So my question is WTF? What the heck is she doing? I mean I see what she is doing literally but... what the heck? Why is she doing that?
