Phew. Finally a UNIQUE level in this long island, and it needs to be since it holds the final Rainbow Drop. Starting at 0:55, past the dark room, in order to reach the Rainbow Drop room, you need to go through the rest of this level in a specific way using specific abilities on specific blocks to reach their exits: First, at 0:55 pick up Fire, and use it again the ice blocks to the left. Second, at 1:08, take on Stone and use it against the clustered blocks to the right. Third, at 1:26, take on Needle and use it on the dotted blocks to the left. Fourth, at 1:42, take on Ice and use it on the frog egg blocks to the left. Lastly, at 2:01, take on Cutter and use it on the lined blocks to the right. By 2:17, you should be right under the 7th and final Rainbow Drop. Take it, and then keep going forward through the level to face one more miniboss before completing it. From there, the final boss awaits at the top of the Dark Castle!
