How to unlock birdo on Mario Kart wii?
It is Easy as can be. All you have to do is set a time on time
trials on sixteen out of the 32 coarses, or set a time on all of
the corses at the begining of the game (since there is 16 at the
start of the game) or if you have all of the coarses unlocked and
don't have a time set for any coarse yet, set a time on all the
coarses so you can unlock both Birdo and Toadette.
