Use the spider bomb at the stairs, where there's a man-eating plant, if u remember bombing it b4 u can get across.
Then, dun use ur sword to hit the spider bomb, use ur shield to block its attack, it'll stun itself (kinda dumb), remember to lure it closer to the path u're gonna run.
Onced it stunned itself, quickly run up, dun roll, pick it up, run like there's no tomoro cross the gap den throw... If not u can throw from the gap as well.
