We bought another pool ring today and it was an instant hit. Mostly the kids use the floating toys for crashing into each other, pulling each other down into the water, climbing on the same toy so they both fall off, and other ways of getting both themselves and everything else exceedingly wet. (Which has on occasion had unfortunate side effects on the laundry drying on the rack next to the pool. Less than ideal positioning, perhaps, but there just isn’t that much space in the flat, sunny part of the garden.)
