Bombard Cliffs, or World E, is the fifth and final secret world of Newer Super Mario Bros. Wii. There is no tower or fortress in this world. It is tied with Sky Mountain for having the least amount of levels. a new type of enemy is found only here. It is unlocked via completing World 6-8: Buried Boneyard. This world is rather unprogressive as completing World E-3 will unlock a path all the way back to World 1-1: Palm Beach.
The theme is a cliff area with many Para-bombs.
