On this week's episode of Supernatural…

Sam and Dean investigate a series of strange deaths caused after children draw their fears.

This leads them to Plucky Pennywhistle's Magical Menagerie, a kids entertainment party place.

Sam and Dean heavily investigate Plucky's and learn that one of its workers, haunted by his brother's death is trying to save the children by using their fears and a bit of magic to eliminate their problems.

The man conjures up clowns to fight Sam, but Dean gives the worker a taste of his own medicine. Dean defeats the unhappy worker and saves Sam.
