OMG!!! This is just super adorbs! 

Mitch and Casey spend their first Halloween together dressed as penguins and since then penguins have been an important theme in their life. When it came time for Mitch to propose, he knew penguins needed to be a part of it.

Finally he was able to get in touch with the Pittsburg Zoo and PPG Aquarium and they helped him with his plan. The two went to the zoo with Casey thinking they won a behind the scene penguin encounter. 

Casey got a huge surprise when Mickey the penguin came out with the ring and Mitch proposed.

Ah so romantic!!!
