In this tutorials I will show you how to make some easy tentacle.

The first thing you need to do is make a cone. When you make the cone, use the settings below.

That should give you a nice looking cone like the one below

Now click on the space warp ripple button.

And draw the space warp to the left of your image so that it is about the same size as the one in my picture below.

Now adjust the space warp to the setting below

Now we have to tell the space warp what image to ripple. To do that, click on this button.

Than click on your cone, And drag. This should make a little dotted line, keep dragging until you reach your space warp, then let go. This should give you an image like the one below.

Now to get rid of that weird little ripple in the middle, we have to move the space warp downward (x axes) When you do this is should straighten out to a nice wave.

Now you know how to make a basic tentacle. If you want to make it like my example image you can keep going. The next step is to clone the tentacle., And rotate it.

Now just slap a nice material on, And you got yourself a tentacle.
