[MAJOR SPOILERS] Need help with the "exit" achievement.

[Some Random Guy]

Before I begin, everything in this post is a massive spoiler, so be warned. If you haven't found all of the hidden easter eggs, don't read anything from this post.

As the title suggests, I need help getting the exit achievement, as in the one for the secret ending. I already got all the eggs and rebirthed the manticore. To the left of the shrine of the 65th egg is a small room with a flute statue, where I presume the ending triggers. However, there is a big block with the manticore's face blocking (pun not intended) the way, and I can't seem to find a way to get past it.

Any help would be appreciated. It's not easy to try stuff out with Mr. Fuzzyface firing laser beams at me.

You can move the block using the wheel on a pedestal hidden two rooms to the right of the incubator room.
