He's an Oompa Loompa!
This is definitely an Oompa Loompa doompity Do! (Sorry, we couldn't help ourselves) as far as kid costumes go. Playing one of Willy Wonka's minions gives Melissa and husband of ten years, Mark Wilkerson, plenty of costumes to coordinate. We could see Mark being a convincing candyman while Veruca gives the Veruca Salt a go.
And their other two boys? Well, if they don't want to rock the green wig and orange face paint of a classic OL, one could go as Charlie.
Our real hope, though, is that she gives birth to a little girl who can go as Clarissa Explains it All while Tucker dresses up as Ferguson. It'd be like Halloween and Christmas rolled up in one!
