How do I get the rainbow potion to work for the boss fight??? I have Sai and I drank the potion before I went into the area where Miss Knives house is but I'm still not getting 3 lives for the boss fight mini game.
Thank you. I didn't know that there was a second potion but I talked to spider before he was small and when he was turned into a small spider but both times he didn't give me the potion. Does it maybe have something to do with the extra pot by the plants or am I missing something?
