Heat oven to 250˚F. Combine cereal, oyster crackers and peanuts in a medium bowl. Set aside. In a small bowl, stir together oil, onion salt, garlic powder, cayenne pepper, thyme, paprika, cinnamon, allspice and brown sugar. Pour over cereal mixture and stir until well coated. Spread onto a baking sheet with sides. Bake in a 250˚F oven for 30 minutes, stirring after 15 minutes. In the meantime, combine pineapple and coconut in the medium bowl (there should be some residual spiced oil left) and stir to combine. Add the pineapple/coconut mixture onto the baking sheet and stir to combine. Continue baking another 30 minutes, stirring after 15 minutes.
