The Dragon Riders are the only patrollers, and make sashes for themselves with "DUMB" on it. Only Snotlout and Astrid wear the sashes. The Twins take the opportunity to not patrol and instead joke around, while Fishlegs quickly gets scared away. Snotlout looses track of Hookfang and is blamed for the vandalism of the Great Hall the very same night.
D.U.M.B is presumably dissolved after Stoick banishes the dragons to Dragon Island due to excessive property damage that appears to have been caused by the dragons.
