I thought that it would be cool if Olimar's down taunt would release the red spray from pikmin 2 on the pikmin in line so that they would get a slight damage, knockback, and speed boost for like 10-15 seconds. The spray should take about 30-40 seconds to be used again. I think that this would make up for the fact that leaf pikmin are kinda weak and it takes time for them to gain power. Any thoughts?
