Hil My name is Lina. I want to describe briefly a building I have visited recently. The most incredible thing about the building is the shape. It’s in the shape of a giant turtle. I loved the shape of the building. It’s so realistic. To enter the building, visitors had to pay Rp. 17,500 for adults and Rp. 12,500 for children. Inside the building, we were able to enjoy facilities, such as a giant aquarium with sharks, turtles and various fish in it, educational games, and a 3-dimensions film booth. I also liked the aquarium; the fish inside the aquarium seemed so close to the visitors. However, I didn’t like the educational game section because almost all the games didn’t work. The officer in the room was not helpful at all. He just sat in his chair and did nothing. Even worse, he was smoking, although there was a “No Smoking” sign in the area.
