Sunday, a kid with an ocean-sized imagination, is nervous about her upcoming ear surgery. Mom and Dad tell her to put on a brave face, but how can she when she has so many questions? Will it be scary? Will it hurt? (And what does it mean to put on a brave face anyway?) When surgery day rolls around, Sunday's stomach is in knots like a triple-tied shoelace. But thankfully, she has her BFF, Octavia the Octopus, by her side. With the additional help of a few "rules," her parents, and some kind doctors and nurses, she soon learns surgery isn't so scary after all. It actually makes her feel a whole lot better!
