There is a script somewhere on these forums to get entities to sit down. I'm sure it's here somewhere, I'll have a quick look for it.
EDIT: I found it. It was as simple as going to the Scripts forum and taking a quick search for "sit". First result yielded this script:
;Artificial Intelligence Script
;Header
desc = Sitting
;Triggers
:state=0:animate=10,state=1
:state=1:setframe=7
;End of Script
Copy that to Notepad and save it in the Scriptbank folder, making
sure that you save it as "All Files" and making the extension ".fpi". Then simply apply it to the character, and voila.
