After school, K.O. was singing along to Gar's, someone was hiding in the bushes K.O. was passing by. When K.O. heard a noise, he looked behind himself, there was nothing, someone was hiding behind a tree and bounced quickly. K.O. responded that he doesn't know what they think what that was and he's trying to be heroic. Actually, there were some tiny dinosaurs. When he turned around, there was a young girl in front of K.O.'s face. He was shocked and fell back. She was tired of him singing and talking to himself. K.O. wanted to know who was she. She says "I am Dendy", and the name of the episode shows up.
