I had a go with the pelting tools plugin last night on a couple of simple objects.
One note, if you're watching the first movie about the basics then its not clear what to do after you pelt it.
The cursor goes off screen and ups the animation bar frames to 2000. Then the animation is run and you see the pelt stretching out. If it is on the default 58 frames then it doesn't fully stretch out. Just a tip if its not clear.
