How can I get past Banzai?


Hint 1 of 11:
You're going to need items that you can only reach after you've taken care of
Mac.  See the previous question if you haven't done that yet.

Hint 2 of 11:
Again, the general idea holds here.

Hint 3 of 11:
You want to irritate Banzai before you can distract him.

Hint 4 of 11:
As in the kind of irritation that might make him itch.

Hint 5 of 11:
If you haven't already figured out, there's a way to reach the area just
behind Banzai.

Hint 6 of 11:
Jump on the springy stones to go back and forth from the areas in front of
and behind Banzai.

Hint 7 of 11:
You want to use the helmet that Mac left as a grinder.

Hint 8 of 11:
In particular, to grind up bread into crumbs.

Hint 9 of 11:
Place the "toasted bread" in the helmet first.
