Underpants Dance is a recurring skill in the Dragon Quest series.
Underpants Dance is learned by the Well wisher vocation at Rank 3, Dancer and Jester vocations through Hybrid abilities in the PS1 version, and the Gadabout vocation at the 6th rank in the 3DS remake. Sir Mervyn joins the party with the dance learned. Humorously, the Almighty is able to do the dance in battle, as well. It can cause enemies to laugh.
Yangus can perform the Underpants Dance after allocating 55 skill points into his "Humanity" skill. It shares a similar relationship to War Cry as Kasnooze does to Snooze. Yangus is seen carrying two pairs of boxer shorts when he uses the ability in battle. Tap devils and Caped caperers are also able to use the dance on the party as well.
