Like Ai no Uta, this song was used in the Japanese Pikmin advertisements.However, they don't have a song album released for it.
Lyrics (roughly translated):
Red pikmin is fire resistant
Blue pikmin doesn't drown
Yellow pikmin jumps high
Purple pikmin is strong
White pikmin... contains poison
(they) live with all kinds of personalities.
From the top of the head comes a sprout From that sprout a leaf grows From that leaf a bud appears From that bud a flower blooms Isn't it pretty when everyone gathers together? Let us bloom all kinds of personalities.
The red sunset is burning A face appears from the blue ocean Born from the yellow star From the purple dawn A white day is starting Aren't the different kinds of personalities beautiful?
