Where can i find the berries for the lost children game?

I'm playing the virtual villagers the lost children and i run out of food, I can't fish anymore because of the algae but I don't have much tech point to go to level 3 on farmers in order to get the fish to get of the algae, anyways i was wondering if somebody ped the whole game and can help me get extra tech points or a cheat the would work... thanks in advanced.
