Rainbow Flower is an alternate ability of the Sunflower's Heal Flower. This ability can be obtained from Rux's Bazaar for 500,000 coins. It differs from the default Heal flower in that its petals have several colors arranged in a rainbow-like fashion. The Rainbow Flower only drops one sun drop at a time but drops them at a faster rate than the default version.
When compared to the standard Heal Flower, the Rainbow Flower drops 37 sun drops as opposed to the former's 36, resulting in 185 health total.
The Rainbow Heal Flower is exactly the same as the standard Heal Flower, but it's rainbow colored! It also knows calculus. OK, no that's a lie. It's colorful!
