Witch Hazel has cast a spell on the LOONEY TUNES characters to help her stop Bugs Bunny from finding the fabled "Treasure of the Old Castle."
Bugs read about the treasure in an ancient book he found in an antique shop, but the exact location of the treasure was a mystery. The book read,
"Somewhere in the Old Castle, there's a treasure that will bring great happiness to its finder."
The book stirred up Bugs' curiosity so he set off immediately to search for the treasure.
