If you've ever played Paper Mario, that's what it's from. When you fuck up baking a cake for the Fat Shy Guy, he throws a fit at the princess and asks where she learned to bake. NOW YOU KNOW.
No worries, mate! Figured since I'd played Freedom Unite and the original that it wasn't from either of those two, so I was curious. Looking forward to Tri; it'll be the first Wii game I've purchased since 2007.
