Rainbow Heal Beam is an alternate ability of the Sunflower's Heal Beam. Unlike other alternate abilities, it only changes the appearance of the Heal Beam to a rainbow color, and does not change the original's effect.
The Rainbow Heal Beam is exactly the same as the standard Heal Beam, but it's rainbow colored! It heals faster as well. OK, no that's a lie. It's colorful!
- See Heal Beam.
- Rainbow Heal Beam, Chesterweed and Party Citron Ball are the only new abilities to be the same as a pre-existent ability.
- If the player heals other plants 25 times with the Rainbow Heal Beam or the Heal Beam in a single session, they will earn the Sun Heals achievement.
