The Tub

I try to maintain two water plant 'ponds' out front - one is in-ground and the other is a tub that I haven't dealt with yet.

I have some kind of critter problem - someting is taking a dip in both, overturning the submerged potted lily pads. I think it's a raccoon. Those are water hyacinths. They're OK when the creature fucks with the tub, but the lilies are not so hardy. I'm gonna git that varmint.
