A raised pond Make it at least 3 feet deep to keep Raccoon's out and give the fish hiding places. Put an upside down plastic milk crate with extra wide openings on 2 sides Top it with a rock or potted plant.
Wood pallet sandbox, with bench seats that unfold to cover the sandbox! I hate sandboxes bc it's like an outdoor litter box for wild critters. Love that the cover will keep them out! Hubby is going to hate that I found another pallet project :D
