A regular real world, but with living animal pool toys - various species, from skunks, foxes to dragons and sharks, various sizes (but mostly big, although still comfy - they still can pass most of the holes and... they re not bigger than humans, except dragons). Also, fun proverb of pool toys - the bigger inflatable the better inflatable are.) The living pooltoys/inflatables is made out of rubber and they have a seams and rubbery insides. They have a light blue plastic anal valves. They're cute, friendly and squeaky! Also, they could speak like humans! They're smart like humans!
Humans created a special nature reserves in various countries with big inflatable population - for example, Wisconsin State, Escanaba River State Forest. Specialists removed all sharp plants and somehow "rubberized" the dirt, causing it to be soft along with grass.
