ahh yes I can help. maybe. had the same problem.
there's a guy in the middle of the "town", but he's kinda high up, he's like talk to my kids using the targeting system w/ Z button, blah blah blah. It also introduces you to just run and Link will jump. so do this, you do it on pillars of ground, then the roof of a house, then a couple more pillars of ground - these are above the river. On the last pillar, theres grass to blow.
Send the hawk shooting down the river, aimed at the monkey on the pillar of ground, as he's holding the cradle. Take the cradle to the lady by the river, and she'll give you the fishin rod. fish by the cat, give the fish to the cat, then follow the cat to the lady who's missing the cat. Then buy the slingshot.
