GreenPleco Original  Plush Plecos are about 18cm/7in long and pretty anatomically correct. Everything is where it should be 

They come complete with suction cup on there mouth for mounting on pretty much anything a typical suction cup will adhere to. They’re made of synthetic acrylic fiber, so no animals were harmed in the making of, and they’re not recommended for children under three. But let’s be honest, most of us are not buying these for our kids, are we?
