Ikea Tarrasque in pathfinder?

[Swaoeaeieu]

So i was reading the old emerald legion thread (http://www.giantitp.com/forums/showthread.php?101587-D-amp-D-3-5-The-Emerald-Legion-Mass-Producing-Ikea-Tarrasques) (wich is amazing). And i wanted to use it as a plot point in my campaign. The PC's dicover someone trying to develop the legionairs and need to stop it from working.

But is there such a thing as the emerald legion or other ikea tarrasque's in pathfinder? Or do i just need to use the 3.5 version in pathfinder?

A Half-Balor moss troll would be a good start. Imbedded ioun stones could take care of the need to breathe and foodstuff, coupled with the Mutant template could allow for immunity to mind affecting effects.
