Certain GIANT Events

If the Devs find an Idea like this, is to have regular people/animals enter the park from time to time. Example: An Ominent Scientist is out around the park looking for you, if they see you, hide or its game over. A reporter sneaks in the park, if they find you they'll drop a package. A stray dog/cat enters the park, if they see you hide or game over. All Giants will be on a few set paths but the timing is randomized. This will make building a bit risky, if you build a bridge they could walk over and destroy it, if you have a tower/house they may seen it and investigate. What do you think of this idea?
