engaging is one thing, but you'd be better off using a cardboard dummy for the biologist since the basic premise is probably to lure more folks down here and from a biological ecosystem standpoint the first thing to have to be said would be for them to go home as soon as possible and each take some of the other residents back home with them - when you've too many 'owners' per square mile of fragile ecosystem already - and it is very fragile - the only way left to go is up, and that will just ruin things even further with more runoff and sewage.
