In her lab, Shuri, Princess of Wakanda was sitting down in a spin chair trying to spin some screws into a gauntlet that had two tiny blasters protruding from it and a small black spider painted in the center. In fact, speaking of spiders, this shooter-looking device seemed very familiar…

At this time, her older brother, T'Challa, walked in. "Hey, little sis-"

The princess spun around and looked at him with annoyance. "Out of my lab. Now, T'Challa!"

She stood up and tried to shove him out, but her brother easily spun around her and got closer to what Shuri was working on. "Is that-"

She sighed. "Fine. Yes, this a prototype of a web shooting device that Spider-Man uses."

T'Challa's eyes widened. "Sis, I know you're a genius and all, but are you sure that you're building it right? What Peter uses is a high-tech innovation he built himself."
"I know. That's why I'm building them based on the designs on the blueprints he sent me."
"He sent you the blueprints for the weapons he uses? How on Earth did you convince him to do that?"
"I beat him in a high-stakes game of online beer pong."
"'High-stakes'? What were you gonna give him had he won?"
"I promised to make him a spider-themed vibranium suit."
"You really would've done that for him?"
"Hell no! I would've just told him that the suit got lost in transit or something."

As she sat back to finish tightening the screws, the king of Wakanda asked his sister, "So, what are you gonna do with this new tech at your disposal?"
"I'm thinking of adding this baby to your suit. A little upgrade for my big bro."

T'Challa rubbed his head with his hand. "Thanks, Shuri, but…"
"But?"
"Sure, it'd be helpful for swinging through our jungles, but it doesn't really fit the whole 'Panther' motif I have going on."
"That's what you're hesitant over? You're the king of our country! If anyone teases you for going against the panther thing, just banish their ass or claw their eyes out."

When Shuri saw him shake his head, she thought for a second. "Fine. Just switch up your identity from 'Black Panther' to...uh...ah, 'Baboon Spider-Man'!"
"That's still a no from me."

Having finished off the last screw, Shuri stood up, slid the shooter onto her right wrist, and started to load the web cartridges in. "We can still utilize it and keep your current costumed identity. We can call it…'yarn-shooters'!"
"Shuri-"
"Yea, yarn isn't intimidating, but it fits so well with the panther motif. You know, 'cuz cats and yarn."
"Shuri-"
"We can even run with it and color the webs to make it look like yarn. I'm thinking we color it yellow, or a light blue-"
"SHURI! YOUR THING IS ABOUT TO BLOW UP!"

Looking down, the princess saw that the cartridges were swelling up like balloons, barely being contained by the shooters that were built around them.

"Wh-" Shuri got out before the cartridges exploded. T'Challa's used his fast reflexes to get himself out of the way of the wave of adhesive that burst out.

The person who just built the now-ruined web shooter wasn't as lucky. When T'Challa looked, his sister was pinned to a nearby wall. Her right arm was pinned to her side under a pile of webbing while her left arm was sprawled out and pinned with a smaller web blotch. Everything from her thighs down to her feet was covered in adhesive. Finally, her face was covered from below her nose down to her chin.

As the king tried to process what just happened, Shuri's phone vibrated. "Speak of the devil, it's Peter," he reported.

The very utterance of his name at this moment sent Shuri into absolute fury. "MMMMMMMM!" she roared.
"His text reads: 'Hi Shuri! By the time I'm sending this, you've most likely figured out either by it messing up your designer clothes or from a complaint from whoever cleans your lab that the formula I sent you to create the webbing was rigged to cause the fluid's pressure to build up immensely when compacted in a small area such as the cartridges. Why did I do that to you? Well, I know that you were never gonna build me that suit if I had won the game, so I decided to have a little fun. I'll send you the non-exploding formula later today. Bye )'"

As Shuri felt a burning rage build up inside of her, T'Challa stood in silence for a moment before saying, "Maybe you're onto something with that yarn thing. After all, yarn is never that sticky."
MMM MMM MM MMMMMMM!"
"Language."
