The Legend of BigPoop

There is a legend.
A legend lost through the passing of time.
A legend that
-if anyone knew it exists-
would inspire hope to all who came across it.
The legend of BigPoop.

-------
Jack and Clara have been friends for FOREVER - ever since Clara moved into Jack's kindergarten class years ago. When Jack begins to develop feelings for Clara, he convinces her to go on a 'BigPoop Hunt,' with him - a search for the infamous creature which used to save people in stories by pooping on the heads of their attackers (totally fake) - just to relive their childhood . What they didn't expect was for BigPoop to actually be REAL, for a leprechaun to be hiding his treasure in the same woods that they are in, or for an ex con to be trying to steal the treasure from the leprechaun, and - worst of all - to get lost in the woods with Jack's annoying 10-year-old sister, Ivy.
Well, poop.
