Tiramisu Tower is the tower in which Saturday hides out and stores all her stolen goods. According to Sir Carrot, the royal guard has known about her hideout for years but didn't want to make the journey because it was too long.
Brambleby, Saturday's butler, is also assumed to live there.
Tiramisu Tower is located in the Doughnut Kingdom, within the Flatbread Flatlands.
The top floor acts as a treasure trove which holds all sorts of goodies, from which our Heroes took Cucumber's wand, Almond's sword, Sir Carrot's spear (until it was broken by Splashmaster), and one of the Disaster Stones.
