From The Prettiest Flower

     "No time!  We have to get out of here!" shouted Minerva.
Everyone ran through the castle hallways, avoiding the vines.  They all looked quite nervous because they were all concerned for the Princess, who was summoning vines everywhere thanks to the machine.  All that running took them to the outside of the castle.  After catching their breath, the travelers, mice, and the princes started drafting a plan together.
"Alright, here's the plan" said Yakko, who was using the tip of his sword to draw out the plan on some dirt.
"The machine and Dot are inside the castle nearby the doors to the garden.  If we don't destroy the machine soon, not only will our kingdom end up looking like Little Shop of Horrors, Dot will also end up in terrible danger from being overloaded"
Everyone looked at the Brain, who looked annoyed from the whole thing.
"Don't remind me" he said.
"Anyways, unlike the forest, these vines will be constantly moving.  So be careful!  We will need to break through these vines or else we'll get caught in them.  Luckily, I have my sword and Wakko over there has his mallet."
Wakko lifted his mallet up in the air.  He then said,
"Ok, so while a lot of us are still figuring out the castle layout, we should be able to go in one straight line as this is a hallway.  There are a couple of turns to take, but it should be easy, right?"

     The travelers and mice nodded yes.  Yakko then drew out arrows to show which ways they have to go.  Everyone understood the plan pretty well.  Meanwhile, the Brain took Pinky aside and they walked somewhere where they could be nearby everyone, but they can't hear them.
"Pinky, are you pondering what I'm pondering?" asked Brain.
"I think so, Brain.  But I want to be the one who wears the tutu!"
"No Pinky.  By helping them out, this could still be our chance to help save the kingdom and I'll still be rewarded!"
"Poit, I'm not sure about that...Prince Yakko looked pretty mad at what you did to Princess Dot"
Feeling more guilty, Brain replied,
"Yes, I know Pinky.  But maybe this will help him forgive me.  So, come Pinky.  Let's go back to them"
"Yes, Brain!  Narf!"

     The mice walked back to the travelers and the princes, where they looked like they were getting ready.  Slappy and Skippy were preparing some bombs and dynamite, the Goodfeathers were warming up their wings and beaks, and Minerva Mink was stretching so she could be flexible.  As Yakko and Wakko were practicing their sword skills and mallet skills, they both shared determined looks.  They were doing this to save their baby sister, Dot.  They were also concerned about accidentally hurting her in the process, but they pushed that thought aside for now.  Yakko got up and then he shouted,
"Alright everyone.  Let's GET IN THERE AND SAVE DOT!"
"YEAH!!" shouted the team.
They all charged into the castle and they began fighting off the vines.

     These vines were pretty wild and they made things pretty hard for the team.  Pinky and the Brain were able to navigate through these vines due to their small size, but it still wasn't easy.  Especially since more and more vines kept getting in the way every time they thought they had a clear path.  They had to constantly go back in order to not get caught by the vines.  They had done this three times, and Brain was getting annoyed.
"These vines are completely out of control, Pinky!" shouted Brain, who had just jumped to avoid getting caught.
"NARF!  Don't worry, Brain!  We can still save the Princess!" replied Pinky
"Right.  Let's keep on going!"
As the mice travelled through the moving vines, they realized that more and more vines were blocking the way behind them and they couldn't go back now, even if they wanted to.  Unfortunately, while they were crawling through some pathways through the vines, some vines began to block off small areas they could crawl through.  Both Pinky and Brain were worried about this and they had no idea where to go.  Brain shouted,
"Pinky!  The vines are blocking our paths!  There's no other way to go!"
Pinky, who was beginning to struggle in vines, replied with,
"Brain!!  I'm stuck!  I can't get out!  How are we gonna save Princess Dot now??  Narf!"
"Pinky, you need to calm down.  I'll come get you and then we can continue-GAH!"
Before Brain could finish his sentence, he got swooped up to where Pinky was and he was stuck too.
"Drat.  Now I'm stuck too."
"ZORT!  Oh no-!  If we're both stuck in these vines, she's gonna remain cat eccentric!" said Pinky, who was getting very worried for Dot.
"Catatonic, Pinky" replied an annoyed, yet guilty Brain
"I guess all we can do is let the team get to the Root Control 1000 and destroy it"
