Template:F3 Castle Street Nights: Litle P's Darkest Hour is an upcoming game for the Wii and WIII. It tells the story of a nightmare that Litle P has found himself trapped in. It has two modes: Dream Mode, for younger fans, and Nightmare Mode for older players.
Very little is known of the plot. In Dream Mode, Litle P's nightmare that he is trapped in takes place in a Castle Street ruled over by Squirtle, Marill, and Polywhirl, the Three Amigoes. In the darker Nightmare Mode, however, Castle Street is controlled by a demonic, devilish Billy McBoberson. The nightmare version of Boberson employs the nightmare versions of Sunnyscythe and Little Squirtle as his henchmen.
