|A Royal Tart, a delicacy served only at the Back-Rubbing Ceremony|
|Location||Royal Congressional Hall|
|Introduced In||"The Other Tarts"|
The Back-Rubbing Ceremony is an annual event at the Royal Congressional Hall deep in the Bad Lands, that apparently entails mutual back-rubs. It is among the most sacred of all gatherings in the Land of Ooo. The event is distinguished for being the only time at which the royal tarts are served. Upon the people who attend the back rubbing ceremony are a lot of Backrubbers. Princess Bubblegum had invented the false risk that she would be decapitated if the royal tarts were not delivered in time. This was so Finn and Jake would not eat the tarts.
