OK, this is kinda like my last one, but I'd actually like this: LBT and Family Guy.
Out on vacation, this Griffins' plans for rest and relaxation are thrown into chaos when their plane crashes on an unknown landmass. They find themselves in the Great Valley, and meet the gang. Stewie quickly tries to rebuild the plane, a la Flight of the Phoenix, but Sharpteeth attack, and the Griffins are stuck in the middle. What the deuce?
