you must build a hut (1 a understand, then a campfire, then the storage and then you can build a hut) then you got a picklock. there is a crate on the island you cant destroy. use it with the pciklock (just press e when its in your backpack). you must use a combination out of the left and right arrow key. you got a map, a paddle. (hm?) and a patrick seestar (its the most usefull
). dig a the red cross (how new
). a pirate come. he wants a parrot. catch it with a net (10 ropes, 1 branch) but just use the right mousekey. then he wants his 3 moneybags. he point the points on the map. dig there. but took some spear with you. then you are finished (with the 1 island)
