Doggy: "We're out of gas and completely surrounded!"

 Alexa: "Looks like we'll have to go through the gallery."

You run into the gallery shutting the door just in time on the infected. You run upstairs looking for a key and you find one in the bush.

You find the red door and unlock it but Father Piggy is right next to you. You run into the room, there's a hole in the glass, you slip through the hole and grab the blue key.
