Mix up the cake batter and add red food coloring. Bake the cake and set aside to cool.
While the cake is cooling, create the Thing 1 and Thing 2 circles and faces by tracing, copying, or drawing freehand.
Once the cake is fully cooled, use the push pop tubes to cut the cake to the right size. Tint the frosting red.
Layer the cake and icing into the push pop containers. A layer of cake followed by a layer of icing. Add another layer of cake followed by a layer of icing. Continue layering until you reach the top of the push pop container.
Use glue dots to attach your Thing 1 and Thing 2 decorations.
Finally, use a little icing to add on some blue cotton candy hair onto the top of your Dr. Seuss birthday treats.
