how do you get marin need help please respond

is this when you're supposed to get her to wake up the walrus blocking the entrance to the yarna desert? if so, then head to the beach where you first found your sword and go the far right corner of it and you'll see marin sitting by the shore. she'll ask you some questions and just say yes to all of them and you'll get marin. then just take her back to the walrus.

i just beat the 3rd level

then what i said was correct. but you have to have traded at least for the pineapple to the bear in animal village. he's the one who gives you the tip about waking up the walrus by having marin sing to it. the order of trading goes:

yoshi doll > bow > dog food > bannanas > stick > honeycomb > pineapple

that's not the end of the trade sequences but as far as you need to go to get the tip.

thanks that was a big help

now what do you do with the pineapple ??
becuz i hav no way of gettin down and goin into the next level under tha waterfall...i suppose u hav 2 find sumt that allows u 2 swim...help me !

go up into the mountains and you'll see a guy waving at you. find a way to get to him and give him the pineapple. he gives you a hibiscus that you give to the goat in animal village who gives you a letter. you give the letter to professor write in the northwest corner of the mysterious woods who gives you a broom. you give the broom to a lady who's always sweeping but now she doesn't have a broom and she gives you a fishing hook and so on.

and to get into the fourth dungeon, go up in the mountains and find some water to wade in that is the screen just above the fourth dungeon (look on your world map) and hop down over the ledge and you'll land right in front of the entrance.

I think the guy waving is called Papahi not that it matters just thought I'd say
