Crank

Blue&White Rider

I have used my park tools tool to undo a nut that has uncovered another square shaped hole, which I presume with release the crank arms. Can someone please point me toward the correct tool to remove this? Thanks very much.

a "crank extractor" is what you want, for a square taper (not octalink) crank arm.
