Actually, I heard that the lemurs, told the hippos, who heard from penguins that the sloths were all in a tizzy and were planning on have a hang-in to protest the over aggressive beats per minute in the rock music presented.  In a follow up one sloth was over heard to say, "I.......felt......very......pressured........to.....shake.....my.......bugaloo........and.......I.....just.........can't.........do.........that."
