"Ooh, hey, I have an idea!" said Mabel.
"Yeah?" asked Dipper.
"Do you still have room in that journal?" asked Mabel.
Dipper went over to the nearby table and picked up the third journal. They had recovered the journals from town square shortly after Weirdmageddon had ended. As Dipper flipped through the book's pages, he soon saw that there were some blank pages near the end.
"Yeah, there's some space in here. Why do you ask?" asked Dipper.
"I was thinking you could do an entry on me." said Mabel. She turned into her true form of a mass of bugs, though the swarm was still formed into her humanoid shape. Her eyes were glowing yellow as she gave a smile made of bugs. "You know, since I'm kinda an abomination now." she jokingly said with a giggle.
"Well, alright." said Dipper. "But could you give me some help filling in the details?"
"Sure thing!" said Mabel with a grin, turning back into her regular form.
So, the two used two of the blank pages remaining in the journal to make an entry on the bugs Mabel was composed of. They debated for a bit on what to name them, but eventually settled on "Weirdness Bugs."
Dipper drew a picture of a pile of the bugs near the top of the page before writing the entry.
"Apparently, these were what everything in Mabel's bubble was really made of. Figures that anything made by Bill is creepy deep down. They can shape-shift into pretty much anything, but they'll revert back to their true bug form under certain circumstances, which I discovered during an incident I'd rather not go into detail on.
Well, we all managed to escape the bubble, but unfortunately we weren't all unscathed. It seems that being exposed to a bubble full of pure weirdness for three and a half days straight kinda messes a human up physically. I'm not quite sure how to put this, so I'll just put it it bluntly. Mabel's now a swarm of the same bugs everything in the bubble was made of. Not to say she isn't still Mabel, she's still the same sister I've known all my life. It's just that she's not exactly human anymore. No offense, Mabel.
She learned to shapeshift pretty quickly, and she usually takes on a form that looks just as she did before being put in the bubble. Mabel, being Mabel, has also used her new shapeshifting abilities, let's call them, to do things such as shapeshift to look like me while she's imitating me, and turn into normal looking objects and hide in plain sight to mess with me. She also used her abilities to help me with chores, so I guess that evens out. I'm mostly glad we got her out of that bubble when we did. Who knows what could've happened if she'd been in there much longer.
Weirdmageddon was ended the other day, but Mabel's still a bunch of bugs. I guess this is a long-term thing.
Mabel doesn't seem as creeped out by all this as I am, which I guess I should've expected. She never had much of a problem with bugs. Great-Uncle Ford and I have been trying to find a way to change her back, though we haven't seen results yet. Mabel doesn't seem to mind the prospect of being a sentient bug swarm for the rest of her life to be all that bad, which is a little concerning if you ask me.
I just wonder how we're gonna tell Mom and Dad all this."
After he finished writing, he and Mabel drew some more illustrations to go with the entry before closing the book and setting it back down on the table.
"There." said Mabel with a grin. "Now I'm immortalized in print!"
