All together!:
♪I’d like to build the world a dong
And furnish it with expansion
Grow a massive dong and sing a song
And do it with a Pokémon
I’d like to teach the world to expand
In perfect harmony
I’d like to hold them in my arms
And keep them company

I’d like to see the world for once
All standing cock in hand
And hear them echo through the hills
For expansion throughout the land
That’s the song I hear
Let the world sing today
A song of expansion that echoes on
And never goes away

I’d like to teach the world to expand
In perfect harmony
I’d like to hold them in my arms
And keep them company
I’d like to see the world for once
All standing cock in hand
And hear them echo through the hills
For expansion throughout the land
That’s the song I hear
Let the world sing today
A song of expansion that echoes on
And never goes away
A song of expansion that echoes on
And n-e-v-e-r g-o-e-s a-w-a-y♪
