if you still die to djimmi even with 9 hp he will say a different game over quote in the final phase like "you foolish cups can't best me even with my wishes"
There's also an easier way to get rid of the 9hp cheat, after summoning game djimmi if you spin around again there's going to be a reverting sound That reverting sound means the wish is cancelled and you have your normal lives again
Fun fact if you go into the place behind the waterfall there is another secret place idk how to get to it but I axedently discovered it but it takes you under every bridge you unlocked I recommend to spin in circles to find the spot!
