I've seen a few "Up" themed cakes, but they usually forget Kevin! I'm glad to see she gets her day in the sun here, being almost as tall as the house and all. Do you think the balloons are crunchy like Necco wafers? Mmmmmmmm... Necco wafers.
Can't you see this cake inspiring an entire room's worth of decor? I like kids decor that can transition through the years. I feel like pink and blue are such baby colors that don't apply quite so well when they become toddlers. Green and yellow are always classic.
