Somewhere, on the edge of a small continent, there's a town. It's called Old Port, because it remembers times of great sailing ships and brave people who used to sail them. Each nook of this charming town has it's own story from distant times.

Old Port - your home town

This is where Tony and Annie live. They are 10 years old and their heads are full of dreams. They have made friends with the Captain, an old sea dog, who traveled many seas and knows lots of tales from distant lands. There were times when they all together set off for long voyages. They got to know faraway regions and people who live there. From each of their journey, they brought lots of presents from their new friends. They also wrote many letters and postcards in which they invited each other to visit their homes. The postman always had to carry a heavy bag, filled with lots of mail. He wasn't very happy about it, but... a letter must be delivered - that's the duty.

Once, on a beautiful July day, as usual the postman arrived at Tony and Annie's door. However this time he didn't have his bag full and he just handed a single letter to the kids. There was a strong chill coming from it, like it has been mailed from a very cold place. It seemed that the other letters got scared of that cold and decided no to get in the postman's bag - that's why there was only this single one.

Here's what was in the letter:

Antarctica - home of your dear friends

The message alarmed the kids and they quickly decided that they couldn't leave their friend in danger! They decided to set out on a long journey. Open ocean and ice fields - that's a challenge even for the most courageous ones.

Tony and Annie decided to help their friends. Would you join them on their journey?
