I made this cake using 5 banana cake mixes. The "river bank" is the mix for cake pops (crumbled cake with icing). Then I sprinkled crushed graham crackers over it for sand. The "stones" on the bank were english toffee pieces. I used regular blue icing for the water, then swirled over it a tube of blue sparkled gel icing to give it glistening water.The animals and trees, I bought through Amazon.com.
