This isnt what you are asking for but I made this with my kindergartners. SO if you need another craft/snack here is a suggestion.

We made the ocean. I gave each kid a clear cup. They crumbled graham crackers in it. Then they scooped in some blue jello. Each child had sweedish fish that they put in their jello. VIOLA the ocean.

That;s all I got for you. Sorry

Oh, you can call the worms electric eels!!!
