If you don't get the photograph, reload your save and try again. They may run away from the guests, they may ignore them and they may stop panicking without any mishaps. Once they're out, things become a little hit and miss. Quickly jump into the ACU Helicopter and follow the Polacanthus around, ready to take a photograph. Reloading a save will likely overcome the problem. The guests may hear the commotion and flee before they get out. Don't be in a rush to let them out - make sure their comfort is down around 40% to give them time to injure a guest before their comfort levels stabilise. You can either let them break out, or simply demolish a fence to let them out. They will behave just like the carnivores and start attacking the fences. Make a save when you see their comfort level drop into the red.

They may actually be happy enough with the size of the enclosure but if you make sure there is no forest their comfort will start to drop. Release the Polacanthus when they're ready and transport them into the small enclosure. Wait until you've released some of the dinosaurs into the first enclosure and have some guests back on the island.

To get them as close as possible to the guests, build a small, concrete-fence enclosure between the Creation Lab and the Viewing Gallery (and close to all those unsuspecting guests.) Once they break out they need to trample a guest before they become content again. This means that there is essentially a timer. The problem here is that the dinosaurs will become agitated and panic when in an unsuitable enclosure, but once they are released or break out they comfort levels will return to acceptable levels. Simply releasing herbivores amongst guests won't do the trick, they need to be panicking.

They they are one of the few with the highest comfort threshold for herbivores (60%). If you've followed the walkthrough to a tee, you won't have released this species yet. Incubate a pair of Polacanthus at the new Creation Lab. The setup is complicated and a little random and the achievement itself seems a little buggy. You need to photograph a Herbivore attacking a guest and it's a little trickier than you might expect. If you unlocked it way back on Isla Matanceros, release and immediately sell a single Polacanthus then skip ahead.
