How do I fluff up stuffed animals that i washed in the washing machine, that need their stuffing re-distributed?

What I do is find a seam that can be slit and easily stitched back, then pull out all the stuffing, then put it back in and resew it.

When that happened to me I just massaged them until they went back to normal. My old comforter would do that, too. Just be patient with it. :)

I always dried them in the dryer, slowly and very gently.

I put a couple of tennis balls in the dryer with my stuffed animals and put it on low heat.
