*Dipper and Mabel's POV*
After waking up at around 12 in the afternoon Dipper and Mabel decided to go ask their great-uncle, Stan if he knew what the fruit was that Mabel found in the fridge.
"Grunkle Stan!" Mabel and Dipper shouted in unison.
"Oh god, what is it? I'm right here." Stan said.
"Mabel found a weird fruit in the bag of apples last night. It was pink and heart shaped. Do you know anything about it?" Dipper asked.
"It tasted horrible too!" Mabel added.
"Well, when I bought the apples I didn't notice anything strange in them. You sure you weren't just too tired last night to know what an apple looks like?"
At that moment, Mabel figured out what the name of the weird fruit was, Love Love Fruit, and in her head, she somehow realized she now has powers. But what kind of powers? How can she use them? She'll need to ask Dipper to help her out with that later. Right now she has to decide between only telling Dipper or letting both Dipper and her great-uncle Stan know.
"Oh my god, guys! I have powers!" Mabel shouted excitedly, not taking any real time contemplating what to do.
Dipper and Stan both turn to face the excited teen.
"What?" They ask in unison.
"I have powers! I know what the name of the fruit was too. The 'Love Love Fruit'. I somehow thought of it just now and I figured out it gave me some kind of powers."
"You should probably lay off of the candy for a little bit kid." Stan says.
Mabel then stops pouring a bag of smile dip into her mouth to say, "I know I have powers! I'm just not sure how to use them yet."
"Do you know what kind of powers you have and just not know how to use them?" Dipper who is willing to believe Mabel at least a little bit after everything they've been through together.
"I'm not sure for either one," Mabel says as she picks up an orange off the table, as she started to peel it, she was thinking of what her power could be. Before she finished ripping off the peel, all of a sudden, the orange turned to stone. All 3 of them were speechless, especially Mabel. Just a few seconds ago she had a normal orange in her hands. But now it was just stone. Shocked by the sudden changed she dropped the orange. Causing it to shatter in many pieces, revealing it was solid stone.
"What the..." Mabel finally spoke, breaking the silence.
"Mabel, how did you do that?" Dipper asks.
"I, I don't know. I was just thinking about what my powers could be and then this happened. You think my power could be turning things to stone?" Mabel asks.
"I don't know if that was the case why would it be called Love Love Fruit? Maybe turning things to stone is a secondary power?" Dipper says.
"Well whatever it is, go figure it out somewhere else, but first clean this up," Stan says motioning towards the dust and bit of stone on the floor from the orange. Having lived in Gravity Falls for quite some time, Stan can get used to any new weird things fairly quickly as opposed to a normal person seeing stuff like that for the first time. "Oh yeah, your little friend Pacifica Northwest was in the newspaper this morning." Stand adds.
"Really? What for?" Mabel asks.
"Apparently she was able to turn parts of her body into diamond. Although no one really knows why. Could be related to your powers Mabel." Stan replied.
Mabel and Dipper looked at each other. Both, without saying anything, agreed to go see Pacifica. If Pacifica received powers from eating a fruit like Mabel, then maybe she could teach her how to use her powers. So after they clean up the stone from the kitchen, grabbed Dipper's new journal, and then they headed off to the Northwest mansion. Once they get there, instead of going through the main gate, they sneak around to the side to go into a secret entrance since Pacifica's parents wouldn't let them come in normally. Once inside they ask a butler where Pacifica is. Since Pacifica's parents generally look down on everyone who isn't rich or powerful, including their own servants, the butler didn't really care who Pacifica was friends with, and was willing to help them sneak around to Pacifica's room.
*Pacifica's POV*
Pacifica was sitting alone on her bed turning parts of her body into diamond, shining it in the light. While she was somewhat excited to now have powers she wasn't exactly sure why she's able to have it. All she knows is she randomly started to hear "Diamond Diamond Fruit" in her head and realized she had powers. Though she didn't know how. 'I should probably go and ask Dipper if he knows something about this in his journal.' Pacifica thought to herself. As she was about to get out of bed to go see the twins, her door opened and in walked her butler and said twins.
"What are you guys doing here?" Pacifica asked, surprised but not displeased to see them, even if it was unannounced.
"We wanted to talk to you about you being able to turn your body into diamond." Dipper said.
"Ooh, so shiny," Mabel said as she started walking towards Pacifica, who had forgotten that she turned her arm into a gem.
"Well, I started being able to do it a little after I woke up today. When I showed my parents they almost immediately called the news to show that their daughter now had weird powers." Pacifica said, almost completely ignoring Mabel aside from holding up her arm in the light for her to see.
"Do you know how you got the powers? Did you eat any kind of fruit that looked a little weird and tasted disgusting? Or hear a name for the fruit in your head?"
"Slow down Pines, I don't know how I got them, I did have a smoothie last night that tasted horrible. It almost made me throw up after just taking one sip, I asked the guy who made it what was in the smoothie and he said he put what looked like a dragon fruit in it. And I did hear 'Diamond Diamond Fruit' in my head not long after I woke up." Pacifica said as she pulled her arm away from Mabel who was touching the diamond limb.
"A similar thing happened to Mabel, last night she found a weird looking fruit that she said tasted terrible and in her head earlier she found out the fruit was called the 'Love Love Fruit'. Then she was able to turn an orange into stone. Show her Mabel."
Dipper then took out a pencil from his pocket and handed it to Mabel who after a couple of seconds of thinking of her new power, turned it into solid stone. Had they showed Pacifica this before she got her powers she would've been speechless, but now she is just surprised.
"Wow, wait if she can turn things to stone, why is the fruit called the 'Love Love Fruit'?" Pacifica asks.
"That's why we're here, we were going to ask you if you knew how I can find out how to use my powers." Mabel replied.
"Well, I was able to immediately figure out my powers. I would imagine it would've been the same to you. Maybe you can just figure it out eventually on your own. Since mine was called 'Diamond Diamond Fruit' I can turn parts of my body into diamond, so I would imagine other fruits would be pretty literal. So maybe yours has something to do with emotions?" Pacifica says.
"That would make sense, although I don't know how Mabel would know how to use her powers," said Dipper. "Hopefully it'll just come to her as you said."
"So I'm guessing you don't know anything about the weird fruits?" asks Pacifica.
"Only what Mabel's fruit looked like, the name, and what it can do so far. I wrote it in this journal." Dipper says as he hands Pacifica the journal he plans on writing down any more fruits he can find.
"Oh, I almost forgot, Mabel," Pacifica said as she started looking at Mabel's fruit in the journal. "When I took a bath earlier I felt weaker for some reason, but when I got out I felt fine, and I only felt weak when most of my body was covered in water, so the fruits might give a weakness if you go into any water. Just a heads up."
"Aw man, so I might not be able to swim anymore? Well goodbye, public swimming pool..." Mabel says as she starts looking at the ground in sadness she might never be able to swim again.
Upon hearing this Dipper grabbed the journal back and started to write in his journal, writing 'These strange fruits might give a weakness to whoever eats them if they go into water.' That was something he was going to test with Mabel later. Pacifica told the twins she had somewhere to go soon and that they would talk later, so after saying goodbye, the twins snuck out of the mansion the same way they snuck in and went home to see if Mabel can figure out what her real powers are.
