Use 17 Power Bombs while pressed against the crumble blocks to overload PLMs and go through the crumble blocks. With Morph, exit G-mode near the item then return to the left, without, exit in the middle of the room to break the crumble blocks.

Anywhere else in the left section of the room requires one more Power Bomb.
