It is the eighty-sixth segment in the series.
Grumpy is appointed substitute King for a Day and must contend with a saber-rattling Gnome King during a peace summit.
Meanwhile, in the castle, Grumpy rang the Bing Bong Bell as Dopey made a mess, asking Bashful, Doc, Sneezy and Sleepy to clear way that mess. Annoyed by his incessant ringing of the Bing Bong Bell for trivial matters, Sneezy told Grumpy that they are not going to answer the bell again.
In the meantime, Queen Delightful and Lord Starchbottom were stuck in a traffic jam. It was expected to take three to four hours to clear up the mess. Queen Delightful panicked. Lord Starchbottom called Happy, asking him to follow the instructions found at the Royal Desk. After, assuring that Happy will take care of it, he reassures Queen Delightful that everything would be fine.
Grumpy tried ringing the Bing Bong Bell for help, but none of the remaining 7D answer, leaving him in a panic. Before he knew it, the Gnome King have already arrived the castle. During the first and second part of the ceremony, Grumpy made some mistakes, leading the Gnome King to ring the G-ning G-nong G-nell, but were ultimately resolved.
The Gnome King declared war after Dopey spit his national beverage onto him during the third part of the ceremony. Grumpy rang the Bing Bong Bell multiple times. This time, however, Bashful, Sneezy, Doc and Bashful answered it. Filled with rage, the Gnome King asked them to get out of his castle. Queen Delightful arrived, he told Happy and Grumpy that he declares war every year and they will eventually laugh it off.
After signing the peace treaty, Grumpy apologizes to Bashful, Sneezy, Sleepy and Doc for his repeated unnecessary Bing Bong Belling. Queen Delightful showed them the Bing Bong Bell bills. The segment ends with Happy asking Dopey to eat the bills and with Dopey belching.
