its the one all the way on the left side, just keep pushing it and it brakes.
You have to push it open.
In the underground lab of Mordred, there is a mud wall blocking your path. Push hard and it will fall down.
you just keep pushing the mud wall... it will eventually colapse.
you don't need to, but if you have the bag of manure you can power up a hover board in a tower with it and it will fly into the mud then you can use it to get around.
It takes a few seconds if you push left on it really hard.
