Digdogger, he could be interesting if he was improved. make him more of a fire ball or something that shoot fire or energy beams or something. I think Manhadela could look really cool in 3D
I'd also like to see the method of defeating bosses improved. Make it more clear exactly how to do some damage. in some cases that was difficult for a first time player in OOT. I like in the original where you could kill a boss in one hit if you placed a bomb well.
