Hi welcome to the forums..!~:D
You would have to use a software, that does that for you...so you would have to make an animation of this character..and then import this character in..as an animation..--Not sure if this would work with 3rd person plugin..

..As that is a different thing..They are not animated..but a series of pictures put together to make up the movements of the character.
If you open up the 3rd person example game--Manage Resources--Then External Folder--you will see how the 3rd person plugin works..
Here are a few of sites that do that..~

That one allows u to make the character--designing it as a flash animation.
