A little while later, the guppies are coloring while Mr. Grumpfish is sitting in a nearby chair reading Merpeople magazine.

"Hey Mr. Grumpfish, what's your favorite color?" Molly asked.

"I don't have one," Mr. Grumpfish says.

"You don't have a favorite color?" Goby asks.

"Nope," Mr. Grumpfish said.

Deema showed Mr. Grumpfish a drawing she did of him.

"Not even greenish brown?" Deema asked.

"No," Mr. Grumpfish said.

"How about black? That's a pretty boring color," Deema says.

"Nope, I don't like black," Mr. Grumpfish grumbled.

"How bout white? That's a very boring color," Deema said.

Mr. Grumpfish started to get really annoyed.

"No! I do not have a favorite color! Now go away and stop asking stupid questions!" Mr. Grumpfish snapped. The guppies, particularly Gil and Oona, felt a little frightened when Mr. Grumpfish snapped at Deema like that. Deema swam away from Mr. Grumpfish.

"Geez, grouch," Deema whispered.

It was time for lunch. Nonny and Oona decided to eat lunch together.

"What do you think of Mr. Grumpfish being here?" Nonny asks his girlfriend.

"I don't like it. He yelled at Deema," Oona said sadly. Nonny began to stroke Oona's hair.

"Don't worry, my love. It's just for a day," Nonny said in a soft, romantic tone. Nonny leaned in closer and kissed Oona on the nose. She giggled. In return, she kissed him on the cheek. He smiled. Mr. Grumpfish swam by.

"Aren't you two a little young to be romantically involved?" Mr. Grumpfish said. Nonny and Oona stared at him.

"No, not really," Nonny says.

"Well keep your PDA to yourselves. You're ruining my lunch," Mr. Grumpfish says.

"What's PDA?" Oona asks her intellectual boyfriend.

"PDA stands for Public Displays of Affection. Kissing is an example of a public display of affection," Nonny explains in a cute, smart guy way.

"You're so smart. I love you so much," Oona says as she put her head on his shoulder. Nonny was mad that Mr. Grumpfish was so rude to him and Oona.
