In some countries, King's Cake - which is a wreath shaped purple, green, and gold cake - is eaten for six weeks! Talk about gaining weight! The traditional Mardi Gras food usually has a baby Jesus baked into it, and whoever eats the piece with the figurine is believed to have good luck for the rest of the year.
The official colors for Mardi Gras are purple, green, and gold. The colors have meaning: purple represents justice, green is faith and gold symbolizes power.
