Make the two chocalate cakes in bundt pans according to package directions. Cool Completely. Set one upside down on a plate with the second right side up so that they resemble a pumpkin shape. Set aside quarter cup of the frosting and tint the remaing frosting orange using the red and yellow food coloring. Cut the banana in half leaving the skin on and place it on the top center of the cake. Tint the reserved frosting green and frost the banana (this is the stem). Cut eyes, nose, mouth and any other features out of the cherry fruit roll up and decorate as desired.
