Halloween at the cabin in OK! Gavin was Indiana Jones this year with a whip that played the Indiana Jones theme song over and over and over again... that song never gets old, duh duh duh duh, duh duh duh...
Ethan also wanted to be Indiana Jones, until Gavin saw it and wanted to be the same as Ethan, so Ethan graciously agreed to be a knight, because he got a cool sword!
