K.K. Safari is a song by K.K. Slider. It has an African or rain forest jungle theme to it, making you feel like you are on an actual safari (hence its name). It also has a very sly theme to it sounding like a African animal catching it's prey. It has a Japanese drum, a safari vibraphone, etc.
These villagers play K.K. Safari inside of their homes once they own a stereo.
