What is an Ugly Cake?

Our entry, didn't win

So I'm still not sure what a fair means by ugly cake.  There was an ashtray cake, a vomiting clown cake, a kitty litter cake, a trash cake and mostly gross cakes.  I'm not sure who won but we are going back so I will check and try to get better pictures.  Our entry, my daughter tried to make a Chinese crested chihuahua.  it actually looked more cute because the cotton candy for hair idea didn't work out so good.  I also plan on going to the state fair where I believe they have the same contest so I'm sure that will have more entries to give us some ideas for next year.
