If you search this forum you will find a lot of techniques for making wiggly lines. Off the top of my head, use shape layers to create the lines and add a "wiggle paths" animator. Also the effect "roughen edges" can be used to create that look.

There's no one button push type of plugin for this one. You have a few options of doing it already. It will involve some roto work ( drawing the shapes and possibly tracking to match the moves) and a combination of wiggle and roughen edges. I prefer the hand drawn direction though, for a more random, organic feel, even if it takes a longer time.
