Here's another set I'll be offering for sale at my school's upcoming Vendor Sale. This one's similar to the Space Set, and I think I'll make a copy for my own use in the classroom. I intend to add a shark, and could easily have these to accompany Slippery Fish, Down by the Ocean, or various other ocean songs and rhymes. And I know the kids will enjoy having these on hand for open-ended play, too.
