The friends are going to have a dragonboat festival, and they're going to meet the real dragon after the race is over. When Rintoo and Kai-Lan come in last place at the first dragonboat race because Rintoo didn't listen to Ye-Ye's instructions and was not following the peeking mice's drumbeat, he grumpily whacks the boat onto a gazebo's roof, causing it to have some difficulty to get it back down from up there. Kai-Lan needs your help to show Rintoo what to do when you feel too mad.
