Describe the bug
King Boo behaves nothing like his original game counterpart during the battle.

To Reproduce
Steps to reproduce the behavior:

1. Enter the boss battle
2. Decapitate Bowser
3. Observe King Boo just flying off for a while, and then heading back

Expected behavior
King Boo flies a bit of distance from the body, and then hovers around, slowly making his way back, and more quickly doing so when attacked.

Fixed in the last few commits, he now behaves more like a regular boo (as in randomly changing direction, moving up and down, etc.)
