Upcoming Penguin Party

The penguins sent out invitations, inviting every penguin they could think of to come to a pool party on Wednesday. They thought if they scheduled it for the middle of the week, security at the zoo would be more lax, and their guests would have an easier time getting out. Do you think I should warn the neighbors about this? And I don't know what the penguins will do if the rabbit party is still lingering on Wednesday. How many bunnies and penguins can one pool hold?
