I'm up to the ark in Nostalgia, where the fair carrots and silver kongs are. I went to the base where a church is and hit the switch. I went back up to the entrance with the eye, and it doesn't appear to be open. What do I do now?
Go up until you are back on the First floor of the ark you'll see a furnace if you have pulled the switch the furnace will burn and inspect it and the door downstairs will open
