Assuming that they DID want to change it to get higher ridership (after all, they make no extra money if it is a little more popular), how would you like to see it changed?
I would like to see them start by making the pre-show area, instead of just one show, filled with a bunch of little one liners - a bunch of talking tiki hads, birde having short back and forth conversations, etc. All around a tropical waterfall.
For the ride itself, first the birds cannot be anywhere as big as Yagu/Iagu however you spell it. I would have a variety show, with a bunch of bird imitators. I was thinking along the lines of bad 70's lounge music, with a bird/flower theme. We could have those white birds singing Una Paloma Blanca, a jaybird Elvis impersonator. Maybe some bluebirds singing Song Sung Blue. Capatin and Tenile could be a couple of ducks singing Muskrat Love, or the ducks could be singing "in the Navy" by village people. OK, scratch that one. African birds singing Midnight at the Oasis? (better change the lyrics on that - though nobody can understand them anyway).
