The Owls not that bad, I kinda liked him in
OoT, he was a kinda mysterious creature ya know? His head spin was quite cute, and the first time he flew you down from the top of death mountain kicked ass!
Tingle on the other hand is just a total waste of a character. Possibly thr most irritating character EVER, although he does have potential...I think he would be good in the new game, but lets make him alot darker and explore his past, kinda like Golum I suppose. We have seen glimpes of his selfish unforgiving side. I.e. charging so much to decipher charts, kidnapping that pink Tingle guy to push the turning device in WW...I know what he's really like.
And leave off Navi, yeah she's annoying at times, but all in all shes a cool chick.
