Liz and her parents went to Tri Nguyen Aquarium in Nha Trang. They saw sharks, dolphins and turtles. They saw many different types of fish. Liz thought the colorful little fish were the most beautiful.

There was a souvenir shop near the exit of the aquarium. Mr. Robinson bought Liz a cap. It had a picture of a dolphin on it. Liz wore the cap all day. Mrs. Robinson bought a poster. She put it on the wall at home.

After their visit to the aquarium, the Robinsons went to a food stall for lunch. Mr. and Mrs. Robinson ate fish and crab. Liz looked at the fish. She remembered the beautiful fish in the aquarium. She ate noodles instead.
