Big Boss, Oops, and Koops use a loudspeaker to create a lot of noise in the village of Greenit to bother the animals. They place the loudspeaker at the entrance of the village and Oops and Koops, who are tone-deaf, begin singing. All the animals cannot stand the awful singing and noise! Pammee who has the best hearing is bothered the most by the noise but she uses earmuffs to plug her ears.

In the Death Forest Oops and Koops are attacked by a huge dark shadow and they are so frightened that they run back to Big Boss' castle. They tell Big Boss that there is a monster in the forest but Big Boss doesn't believe them. Back in Greenit, Yoohoo and his friends are shocked because the village had been ruined overnight.
