get a limocerous

what you do is you watch pest and see which side of you garden he enters from, then once
you have found out which side go to costolots and buy a fence and on the side which pester
entered from put fence along the side 1 square away from the side (basically go to the
side he enters and plzce the fence all the way along that side). then on the outer edge
dig water along the edge so that there is a small stream down the outer side of the fence
and then you will never have a problem with pester.(asuming you have the biggest garden).
p.s. it will also stop ruffians some of the time.
