Kick all of Merlin's soldiers into the T.N.T. pit. Then, use all of the T.N.T.s to burn down the doors. When you reach Merlin, super punch all of the spells, but do not super punch the T.N.T. Grab the T.N.T., go near the crystal ball, and flame the T.N.T. Go up the stairs and flame Merlin three times. Then, go down and flame Merlin two times. If you defeat Merlin, you will hear him say ''Ohh. never saw that coming''.
