Creating the biped was the easy part editing the biped was the hard part. I stated of by creating the biped then going to motion panel and turning on figure mode on. I was able to manipulate the biped to fit my frog mesh. I spent hours moving, scaling, rotating more moving, scaling and rotating until I got half of the biped all lined up with the frog mesh.I then copied the right leg of the biped and pasted into the opposite position on the left leg of the biped, I then did the same for the arms.
To make the jaw I used the ponytails of the biped so that I could make my frogs mouth move.
