Friends, gather around—GO GO!
Let’s go now! Punch it—Helloooo!!

Hey, yesterday I kinda messed up,
Tripped and fell, couldn’t help but laugh.
But if you're here right next to me,
Every day's a—Ah! Big Bang Galaxy!!

Like stardust dancing in the sky,
Your voices reach into my heart.
(Ready! Set! Go!!)
At the edge of light, it's calling us!!

Friendship punch, GO GO! (GO GO!)
With you by my side, I'm happy, yo! (PUNCH!)
Worries? Punch them all goodbye!
Yeah! Yeah! Smile and fly high!

Shining bright, beyond our dreams,
Even a tangled heart will melt away.

Phase 3
Friendship punch, GO GO! (GO GO!)
Echo through the world, hey! Hey! (PUNCH!)
With you and me, let's paint the unbelievable!

Even rainy days don’t bring me down,
Forget the umbrella, let's run right out!
Your smile’s like magic, don’t you see?
Turns the gray into a rainbow!

Inside the rainbow, your aura sways,
Let's piece together this puzzle of love.
(Ready! Set! Go!!)
We’ll paint a miracle!

Friendship punch, GO GO! (GO GO!)

With you here, I know I’ll be fine.
Small happiness grows so big,
