Thanks everyone! I'm happy with how everything turned out. It was indeed perfect. I sit back and laugh now thinking, "That's what I was so stressed out about? It was easy!"

Now, to explain the critter...

Andy and I are both into Star Wars and costuming. When we first met in passing he was wearing a Boba Fett costume and I a Darth Maul costume.

He also had a Tusken Raider costume (aka Sand People). After we started dating, we built a female Tusken Raider costume for me and as a joke "made a baby". He was named Spimmy (short for Sand Person + Kimmy) by our friend's 8 year old daughter.

For the wedding a friend gave us a doll tux so Spimmy could fit in. We get teased that Spimmy's now legitamite.

The figures on the cake are also Tusken Raiders and the creature with them is a massiff to represent Kia.

Here's Andy and I in the costumes:
