Philadelphia Zoo opens a new home for penguins.

PHILADELPHIA ZOO (WPVI) -- The penguins at the Philadelphia Zoo are getting settled into their new home.

Penguin Point opened Thursday morning, where the polar bear exhibit used to be.

22 penguins have moved in and are enjoying the pool that's almost 20 times bigger than their old one.

There's also an underwater viewing area for visitors, and plenty of rocks for the birds to explore.
