I got these for my DD for her 2nd bday, and both my girls LOVE these. I have been throwing out moldy bath toys left and right, so it is nice to have toys that they like- and that don't hold water. They dry out nicely, I even brought them on our 3 day weekend to VT. Basically these are pieces of foam that stick to the walls like a sticker. Highly recommend, they have tons of diff themes, and this one was only $7.22 on Amazon.com (and I have free shipping through Amazon Prime).
