Frosting the Jungle Cake

Today while I was at school, my mom baked the cake for me.  It's a chocolate cake.  I started with green and blue buttercream.  For the blue, I used a bag with no tip.  That makes round lines.  For the green, I used tip 1M.  That makes giant stars or the swirl on a cupcake.

I made my river first.

Then I covered it with big green stars.

Then I put more frosting on the river.

Now I'm ready to make my animals.
