Query: Long-lasting constructive bathtime fun

My parents got me and my siblings these simple foam building blocks from Edushape almost 20 years ago. I remember HOURS of great bathtime fun with my brothers, constructing rivaling towers, great ships, and floating homes for our foam animals. We still have a few of the original set of blocks. And some have tooth marks or corners that were chewed or ripped off, but all in all they are in pretty good condition. They have held their color, they still float, still stick together (when wet), and still stick to the side of the bathtub. I'd call that durable.Now that I have my own son, I've hunted down more of these same blocks so that he too may have creative constructive bathtime fun.
