You’ll first battle Efreeti. Defeat it and Kine will be free. The next area will side-scroll. There are bouncers behind you along with thin ice and icicles falling ahead. Go through the door quickly before the side-scroll pins you in. Fall between sets of weeds in the ceiling and shoot fire to melt ice blocks. Swallow blocks and enter the door to a secret room. Melt more ice blocks with fire then grab the Rainbow Drop. After you pass cannons, you’ll see the door above a spike pit.
