They may not face many in New Zealand, but Kiwi children rate dangerous animals as their biggest fear.
And when our kids grow up, they want to be professional athletes, according to a global survey.
But children in developing countries want to become people who help meet the the basic needs of their community, such as teachers, doctors, nurses or dentists.
The third annual Child Fund Small Voices, Big Dreams survey was released today in conjunction with Universal Children's Day.
More than 6200 children across 47 developed and developing countries - including 720 from New Zealand - were asked about their hopes, dreams and fears and their thoughts on the environment.
Despite 60 per cent of Kiwi kids experiencing earthquakes, they said they were more concerned about pollution than natural disasters.
And when they were asked what they were most afraid of, dangerous animals trumped violence and crime, the world ending and the dark.
Alex Gordon, 10, doesn't like spiders - especially when they get too close or try to bite you.
The student at Kauri Park School on the North Shore said he also didn't like the dark. But that's because "you can't see properly so you can stumble into things and hurt yourself", he said.
Violence and crime is the top fear of children in war-torn developing countries such as Afghanistan (30 per cent) but in Sri Lanka, children most feared ghosts (40 per cent).
Shona Jennings of ChildFund NZ said Kiwi kids' fear of dangerous animals was one of the most surprising results of the survey.
And when Alex grows up, he wants a part-time job as an actor and to also be an architect. But classmate Stella-Rose Pirie-Marsters, 11, wants to be a netball player.
In New Zealand, 18 per cent said they wanted to be a professional athlete. Children in developing countries, though, most want to work in medicine.
