Easter is not a religious celebration in Sweden and Finland; more secular. Children dress up as witches,"Easter Witches", wearing long skirts, headscarves, and painted freckles. Armed with broomsticks, they visit homes, recite rhymes, and exchange well wishes for Easter goodies.
In the Czech Republic, there is a tradition called Easter Whipping. Basically boys will make whips out of pussy willow sticks and they will whip women(lightly) to make them fertile. Women will thank them by giving them fresh eggs.
Chocolates would not hold together in the steamy jungles of Papua New Guinea so, instead of sweet treats and colorful decorations, people dress up their trees with tobacco and cigarettes and use them as places of worship leading up to Easter. The tobacco and cigarettes are handed out after the service.
