put your game on 1/2 speed. and make sure med tech is as high as it can go if you have the points. the longer your character lives, the better chance you have to get the right event.
there are actually several different events that could bring another character to the island, including the crate of babies, a barrel of babies, and a mysterious person in the trees. any one of them will prolonge the life of your village. if food is a problem, pause the game and wait for mushies to pop up.
