The 7D

Queen Delightful has Doc invent a Thingy so that her upcoming announcement can be heard even in the next kingdom over. While Doc tries to find someplace quiet to concentrate on the plans for the Thingy which leads to him working on the plans in the Tranquil Desert, the other 7D turn to Lord Starchbottom to teach them how to be quiet. When Doc's Thingy is finally created, Queen Delightful's invention impresses the ruler of the next kingdom over to have a Thingy made to respond to Queen Delightful's announcements.
