Catch the evil penguin Gromit (Wallace & Gromit 'The Wrong Trousers' episode) This was my 4th cake (my 2nd 3D cake - I made it for my son's 4th birthday). I covered the cake with fondant on a very humid night and the fondant was melting on me! Big mistake!! Think I should have added 'vegetable gum' to make the fondant a little harder. I did intend to make the train similar to the one in the 'Wrong trouser's episode, but it didn't quite turn out that way. Anyway, after many patching work, I managed to rescue it & finished the cake in 13 long hours! Glad my son loved the cake!
