A-tong: I'm back.

Mr. Wu: Hi, A-tong. How was your school trip?

A-tong: Great! My teacher took us to Blue Water Zoo. It was so much fun. My classmates and I had a very good time. Dad, do you know what Mola mola is?

Mr. Wu: I have no idea. What is it?

A-tong: It's the most interesting fish I've ever seen. It looks like it has a big head but doesn't have a body. It's so special. I hope you can see it, too. There are so many interesting fishes and sea animals in the water zoo.

Mr. Wu: It sounds interesting. Maybe we can find time to go there together. We can also take Grandpa and Grandma with us.

A-tong: How about next Friday? It's a holiday. You don't have to go to work, right?

Mr. Wu: Right. Call Grandma to see if she and Grandpa have time on Friday.

A-tong: Yeah!
