I literally can't unclog the toilet to get the last tie I need for Silent but Dadly. I've tried free play, I've tried story mode, I've tried using the disguise, and I've tried just sneaking through. I literally CANNOT get this last tie... advice?

oh bud 

This tie can only be collected during a normal playthrough of the game, as the area it is in is locked during free play. After finding Tommy, Stacy, and Scarlet, Scarlet will ask to meet at the top of the shark tank. On the way, Octodad passes through a locker room.
