Okay, so there is a way to get to it. Ya just gotta outsmart the system. What you do is you need a couple helpers, or a double account and your brother. You dodge all the goats except for the last two. You take a double or a helper, then get into the fight, get defeated and they have to stay on the defeated screen, same with the gruffs, then you, with your account will be able to wall right past and get the toolbox.
