DIY Pokemon Ball cake

So I recently went to Sams Club looking for a Pokemon cake for my sons 9th birthday and they didnt have anything I asked for just a plane white frosted cake, no edging, nothing but a flat white cake I went to Walmart bought 2 things of white frosting and a squeezable tube, a little one, of black frosting. Also need red food coloring I turned one frosting can into red and left the other white Using a cake piping kit I did the red first, then the black in the center a d lastly added the white to the bottom. It didnt take long and it turned out fabulous! Dont limit yourself to what the stores have I wanted to decorate it but didnt want to spend the time baking!
