Isn't this bin cute and inviting? What baby or even toddler wouldn't like it? All you'll need for the base material is some Roasted Seaweed Snack from Trader Joe's. I'm sure there are other stores that sell something similar as well. This one is great because it provides a new texture for babies. It's crunchy, very thin, and a bit oily. Definitely some new textures to experience. Then just add in some bath toys that would be in a pond/ocean/body of water.
