I'm pulled to the natural habitat side of tug of war because the penguins are getting hot and hard to manage. The penguins are also getting home sick. Also, Mr. Popper got put in jail so the penguins were too warm. For example, even the young penguins were hot. Admiral Drake came in the nick of time to get Mr. Popper and his penguins out of jail. The proof that the penguins are getting hot is that they look sloppy and look sleepy all the time. This is page 125.
