Danger Above 7-8 (aka Bus) is the 8th level of the 7th theme in Danger Above. The reason it is called "Bus" is because the pigs' fort looks like a bus. It also fits the city scene.
loft the first White bird to bomb one or two ice blocks to the right of the baby pig atop the bus. Use the next White bird to blast the mustache pig on the left side. Lob the Black bird through the damaged roof, having it come to rest at the bottom of the structure.
