When Gumball woke up, there was a beautiful doe sitting on his chair grooming her fur. She had a cheerleader's top and skirt which were mostly orange. Her top's bottom rim curled outwards. She was humming Amazing Grace.
"Who are you?" Gumball asked the beautiful doe.
"It's me your sister, Penny," She replied.
"I thought you were Prudence or somebody!" Gumball laughed.
"I am Prudence. It was just a disguise," Penny explained.
"Why did you need to disguise yourself?" Gumball asked.
Penny laughed anxiously.
"Uh..." Penny mumbled.
"It's alright, sis. As long as you're with me, I'm alright," Gumball apologized the doe. "By the way, you look so beautiful today..."
"Like usual," Gumball whispered.
Penny blushed.
"Anyways, how are we going to communicate with Bobert and Carrie?" Gumball asked.
"Through Skype," Penny replied.
"Okay," Gumball nodded. "Not to be admorphistic but you look so s..."
"Yes?" Penny cut Gumball off.
"Nothing," Gumball lied, even if he was about to say sexy.
"Okay," Penny nodded.
"So, why are you grooming your fur?" Gumball asked.
"Well, it gets quite serious when I don't," Penny replied while grooming her fur.
Gumball shrugs.
"Anything special today?" Penny asked.
Gumball knew that she was talking about her 13th birthday. He had to keep the surprise Gumball has for her.
"N-n-nothing today," Gumball replied nervously.
"Okay," Penny said disappointed. "I'll go downstairs."
Gumball ran to the door and blocked it. Penny stopped.
"Gumball, why are you stopping me from getting my breakfast?" Penny asked.
Gumball stood there for a moment and thought for a reason.
"I'm going down to see what's wrong myself," Penny said.
"Just let me think about," Gumball said. "Anais please finish now!"
Gumball ran to the front of Penny and tried to distract her.
"There is a dead chicken in our kitchen," Gumball said.
Penny was slowly getting to the dining room. When she eventually arrived, Darwin was on a portable ladder taping on some banners. Gumball sighed.
"Happy birthday, sis!" Gumball greeted Penny anxiously.
Penny hugged her brother tightly. She let tears of joy roll down her cheeks.
"Nobody had ever done such a thing to me," Penny said.
"Not even your family?" Gumball asked.
"Not even my family!" Penny replied.
"Who is she?" Anais asked.
"She's Penny," Gumball replied.
"Happy birthday, Penny!" Anais greeted the doe. "I just didn't recognise you the way you look like."
"It's alright," the doe forgives Anais. "Nobody does."
The doe once again, hugged her brother. The brother she wouldn't forget.
