I recently got married and this is my awesome custom-made wedding cake. My husband was played by Luigi and I by Princess Daisy. The best man was Mario and the Maid of Honor was Koopa Troopa. The Officiant was Flying Goomba.

My husband is a huge half-life fan, if we had had a cake at our wedding I'm sure it would have been this!
