If you picked up the Bottle Letter on Deserted Isle you will be given the option to travel to La Chef Beach, it is best to travel here before Caldoaxa Ruins as it will give you the ability to cook food, a very vital skill. There are two ways to arrive at your destination. Sleeping in the bed will take you to your destination right as Terry wakes up. The other way of getting there is to wait it out, time does not pass while you are in the menu but if you are moving around the ship it will, a good way to use this time, if YOU have time is to do laps on the deck of the boat, it will increase Terry's speed which can be helpful in both saving time getting from point A to point B and escaping enemies when your health is low.
Upon arriving at La Chef Beach, you will be greeted by a naked boy covering himself with a frying pan. He will tell you he is training and drying his clothes. Just then a monkey jumps in and puts his clothes on and runs away with them. The boy will ask you to get them back for him. Run into the cave that the monkey went into to try to catch it. As before fight or flight against the creatures in your path, fighting is more beneficial though. In the second room you will notice a fork in the path, take the left one in this direction you will find a treasure chest below which contains some gold, and if you take the path up it will lead you to a couple of red pill bugs. In this same room there is a hidden path to the left, take it and open up another chest to reveal a fruit knife, you can't equip it yet but you will be able to soon. Head back into the previous room and take the path that the monkey took, South. This is a good time to begin saving up tech points for the upcoming fight. In this next room if you stick along the right wall you will find another secret passage to a chest with a key inside. Keep going and you will see the monkey again, go to the right to get some kills for some tech points. At the end of this room you will find two red worms, which have a chance of dropping tomatoes that can be used to heal a little health. This path is a dead end, head back into the last place you saw the monkey and head North. You will see the monkey shivering with its backed against the wall about to be attacked by a panther. Go to fight the panther, unleash a couple Trickles and he should be finished off. The monkey will then follow Terry, lead it out of the cave, make sure it doesn't get stuck on something or you'll have to go back into the room to get it back.
Once out of the cave the chef will tell you he has become a new man and no longer needs the suit and says you can have it, pick it up and you've unlocked "Mr. Cuisine" Change into the clothes right away and start cooking any meats you have on the fire next to him to gain some edible food and increase your cooking level. Go back into the ship and talk to the Professor then set course for the next destination: Caldoaxa Ruins.
