Read and fill in the gaps: finally, first or then.

Last Sunday my friends and I had a great time!
We went for a walk in the park. There was a lot of snow. We decided to make a snowman \(снеговик\). ... , we made three big snowballs. The first snowball was big. The second was smaller than the first one. The third was the smallest. ... , we took three sticks: one stick was a 'mouth', the two small sticks were the 'eyes'. We made the nose out of a carrot. ... , we put the pot on the snowman's head. We were happy. We had a lot of fun.
