Boss Battle Reference/Analysis

So for my boss battle I wanted to do something like a mix of Bowser from Super Mario World (Where he throws things at you) and Raphael the Raven from Yoshi's Island.

The elements include:
 - Throwing/dropping something at the player. (Bowser)
 - Getting faster with each hit w/ visual cue of getting faster. (Raphael)
 - Moving about the 'room' in a specific pattern. (Bowser & Raphael)

Fight Layout:
 1. Boss Appears, boss music begins.
 2. First phase of fight, the boss moves around in a simple back and forth motion. Occasionally throws out bombs to damage player.
 3. When the boss is at 50% health, he dissappears in a fake 'dying' animation and returns as the final phase.
 4. Final phase; New music starts, boss throws more bombs and moves erratically.
 5. Boss dies, player wins. Yay.

Bowser's Fight:

Prepro - Arena (Island Arena)

Theme: 
   The theme I want to go with for this level is a tropical island. It will have typical tropical flora, as well as a color scheme that reflects your usual 'tropical' things.
Location: An island in the ocean. The arena is on this island.
Time of day: Mid afternoon, a bright-eyed, bushy-tail sort of mood to get from it.
Color Scheme: 

Visual Trademark: The giant volcano that has a snake sprout out of it.
