The main part of the animation involved the character talking to each other. To make the jaw move I used the ponytails of the biped by rotating and setting key frames so that the frogs mouth move up and then back down.As well as the mouth moving I have made the characters eye blink when they are taking to make them look more frog like. I did this by using the eyes and rotating them down setting a key frame then rotating them back up because, the back of the eyes are green it makes it look like the frogs are blinking.
The last bit for animating is the old frog blowing up and up until he goes bang. I did this by using the spherify modifier to increase his size to make him look like he is taking in air and blowing himself up.
