Kan-the-sloth and Edano-the-sloth mumbles, "...reconsider the nuclear power and shift to renewable energy..., etc." The real sloth urges them to talk more loudly and clearly, and encourages them by saying, "it's okay to say no to the nukes!"
In the meantime, the voices from the grey people get noisier and noisier, "The nuke is safe!" "We need more electiricity!""More development!""Economic growth!"
