Museum of Happiness

"There's a new happiness exhibit...at the Museum of Happiness...that I'm dying to see!"

- Chuck

In The Angry Birds Movie, the Bird Village is known to have a Museum of Happiness.

Overview
The Museum of Happiness first appears after Matilda suspends classes at the Infinity Acceptance Center when Bomb accidentally damages it due to his unstable abilities. Chuck has expressed interest in going to the Museum with Bomb and Red to pass the time with classes being unable to continue for the time being.

It can be speculated that the museum was constructed to tell of the birds' happy and carefree lives, prior to the Great Egg War.
