Wow...this deserves a higher score than it is now.
It must have taken a LONG LONG time to figure out how to create a rhyming symphony of Pokemon names. That Poke-rap was somewhat considered a fiasco when the series first started out (some parents accusing it of being subliminal messaging) but I felt it had a bit of a rhyming effect...and it's even avaliable on I-Tunes download (i think it's still downloadable).
But point being said...it must have taken a long time....only thing I felt it lacked was a chorus.
Like how they say...."With over 150 different kinds of Pok-E-Mon! etc"
But making the names rap is the real challange.
Perhaps is you give the idea to Nintendo...they will make a full length one for American Television. But then again...it might be better as simple fan work, yours to claim and yours alone that is.
Good Job!
