I made this cake for my husband.
For Mug: i used cookie cutter to cut a sheet cake and stack it with whipcream then covered with a white MMF fondant and painted yellow food color to get a shiny effect. Then used a wire guage bend to support the plastic beer bottle(from dollar shop). Used mini marshmallow for froth.
made the handle a day before and dry to hold stiff.

FOR EGG: I cut the white fondant for egg white and candy melt for egg yolk sprinkled some lose tea seeds for pepper effect.

For Chicken: Make the cake as desired shaped then roll it in the kellogs, insert the bubble bee straw and stick mini marshmallow at the end painted with brown food color.
