Modding Help Animating

What is the best way to animate a tentacle that will follow the mouse;
-splitt the tentacle into multiple png and "animating" it via a script?
Or
-draw the tentacle in a single png and animate it by frames?

 

script would likely b best

 

whatever script you have that can reference multiple image files could also reference frames.

 

it would probably actually b best to hav script call on the multiple parts from 1 image file, that way its still 1 image file, but still pointing directly at the mouse
