Wiggle??? I would think you want to distort.
To wiggle you would add the wiggle expression to position and probably rotation. Type "wiggle" in the search help field at the top right corner of AE and check out the help files and community resources for examples.
If you are new to AE I strongly suggest that you spend some time here to get a handle on the basics: Basic AE
You need to convert the vector layer from illustrator to a shape layer. The clue comes from the first couple of sentences in the teaser tutorial and from the timeline:
You'll find the wiggle command under the Add button at the upper right.
Again, sounds like your are new to AE. If so try using the search help field. Typing wiggle shape in the search help field will bring up instructions for wiggling a path, Shape attributes, paint operations, and path operations for shape layers in After Effects
Wiggle path works best on stroked paths, not so predictable on filled shapes and it may not give you what you want on the water layer because it only effects the edges.
If there is a texture or gradient applied to your water layer it may not come through when you convert the layer to a shape or you may end up with a bunch of separate shape layers.
I think what you really want is some kind of distortion. Maybe even a pre-composed Fractal noise layer used as a displacement map to make the water look like it's moving.
I figured I needed to convert it to a shape, I just wasn't entirely sure. I'm taking a class for Adobe Suite; I will eventually learn all the ins-and-outs of the program! Thanks for the assistance, I have about a million things on my mind. I may have come across as a youngster attempting to demand answers for a program they don't fully understand.
I don't fully understand it, but it is a requirement to learn this program to graduate from my college and receive my diploma.
