Voices in beginning of Ice Climber music (Brawl)

[Boo Destroyer]

You know in the first part of Brawl's arrangement of the Ice Climber theme, there are these odd voices...

Has anyone managed to figure out what exactly they're saying?

 

[Uniju]

I don't play Brawl often, but isn't it something along the lines of "let's do this"?

 

[Weasel]

I hear "hey guy" but that's about it.
