Personally I think they r there 2 annoy people.they r buried in the ground like fosils,but
when u go ova the crack u fall in.If ur lucky u get 2 see sum of ur residents fall in the
cracks 2!

Dig up all the holes in your town for a whole week. Get all the pitfall seeds you've got
and stick them in the ground in square shape. If someone is dumb enough to walk into one,
when they get back up they'll fall into the next one! ;-D
