Brooke was tired from exerting so much of the strength he didn't actually have a body for so he said, "You will have to sing the song of repelling to them now. I... *yawn* I..." He was trying his best but despite his best efforts he not only was tired from exerting so much strength but from his own tecnique he used that put creatures to sleep. He thought he should try to do something but he was positive that the song of repelling would get rid of the rest of the Sea Kings so he gave up. And much like the first time they practiced together Brooke colapesed backwards falling asleep once more.
