Deuce receives an email that says he's the heir to the royal butt throne. Soon, he‟s crowned King Deuce and is given the keys to his bouncy castle. Zack, as his human, is the royal jester (although Zack interprets it more as “puppet master”). At first, Deuce is making all sorts of crazy proclamations and such, but soon they have to reap the ramifications. Being a monarch stinks. If only there was an egotistical, evil butt they could trick into taking the throne… / Thanks to an awesome Bummy Rippa movie, Zack becomes obsessed with history and the famed Porcelain Throne of King Tush-ankhamun. Using the diary of Smellbourne Sterne, Eleanor's great grandfather, Zack, Deuce, and Eleanor set out to find it and prove their awesomeness to Silas.
