I made 3 total mistakes, 2 on the Cera game, and 1 on the Spike game. The deal on the Cera game was that I simply didn't know how to do it at first. I clicked, but the rock still hurt her!

I finally beat it without further hinderance by rapid-clicking. The mistake at the end of the Spike game was just a 'Murphy,' I guess.

I do believe it helps to have played through The Lion King for the SNES, as I and others here have.
