In The Arena where the hero can fight The Tiny Scourge, there is house by the hunt door where the play comes in. This house looks normal at first, but, upon closer inspection there is a hidden button/lever that can be pressed/flipped but upon doing so it appears to do nothing.

Is this a bug or Easter egg?

Btw, I can’t show it cuz this is my first time seeing it and I already pressed it but in the picture the button was revealed by standing where I am.
