Slimed (2010) [Blu-ray]

Nature is under attack and Ranger Rock Rockerson is ready to shoot someone in the face. An ill-tempered park ranger and a peppy bible salesman hatch a harebrained scheme to save a nature preserve from government shutdown. Deep in the wilderness, they discover that the park has a much bigger problem: a mysterious and sinister toxic slime that is oozing its way towards destroying not just the woods but the entire free world. This dim-witted duo must come together to battle incomprehensible evil, uncover endless stupidity and avoid exploding children at all cost.
