IK Chain questions

Using the PLE Animate Pro 2 version, and I am trying to make an IK chain like a tail wagging. Is that possible? If so, I can’t figure it out. Any help would be great. Thanks!

Draw your tail in as many parts as you like…
Create a continuous hierarchy…
Then animate the tail using the IK tool…
If you like, here is a short video demonstration:
(no sound, it’s all fairly easy and self-explanatory)
