Wedgie and Gizmo's humans are taking their first family vacation to a campground by a lake! And their pets are too destructive to stay home alone. Wedgie the corgi is super-excited. He can't wait to chase squirrels and poop in the woods! But Gizmo, the evil genius guinea pig, has no time for games. He must convince the forest critters to join his Evil Horde and help him take over the world - one tent at a time.
