pink murex

If you go to the island of the where suzy lives, you will see a + shaped pond. You have to go diving in that. To get to that island you have to build a canoe which is the next area from Mr Chef's house.

Okay, so to trade with Ms Weeder, the gardener, for the lime seeds for Chef Butcher, you need to get to the far north-west of the island. To do that you need to create the raft-boat thing made out of a fallen tree which is located to the right of Chef Butcher's home. You will be needing a hammer and chisel to make the raft-boat. Once you have those things, you tap the fallen tree and it will say "Make". This process takes three days because you need a lot of energy to complete this project. After three consecutive days of working to make the raft-boat, you will have finally finished it. Go back to your shelter to rest because it will not let you travel until you have enough energy. Return to the raft-boat and set off in it. You will reach the far north-west of the island soon after you have left. Firstly, follow the arrow straight up. You can explore the other areas later. You will arrive at your destination. Keep on diving in this plus-shaped lake until you find the pink murex shell. It may take you quite a few dives. Then, use the map to get back to Ms Weeder and trade for the lime seeds. Give them to Chef Butcher when you have the mango. You can also get the mango from there as well. Hope this helps! ^_^
