EAT YOUR ALL BOOGERS

I got my bike even when i didn`t beat whitney yet... It`s kinda confusing but i assume you
just need to beat whitney. But theres a something thing before i got my free bike... I
just can`t put my finger on it of how to remember... But when you get the bike the bike
seller he will say its borrowed for you... When you ride more often around goldenrod
ciy... He`ll call and say that for sponsoring his bikes he`ll say thank you for you too
keep the bike.

Hope it helped!

Ps. I`m smarter than all of you boogers!
