why did they build a house on the ogre's head?

Answer 1

There are two ogres, the City Ogre (Nan Belu) and the Jungle Ogre (Taw Belu). The city ogre's head dress is topped with a jewelled spike, the jungle ogre's with a plumed crest. Their dance is mostly a show of evil power and strength, and the ominous music, combined with stalking steps, creates a most chilling mood. After chasing the Monkey away, they chase each other and engage in hand-to-hand combat. The city ogre always wins, and he exits chasing the jungle ogre.

Answer 2

Because they could.
