It's a normal day in the TARDIS, Tegan, Nyssa, Adric, and the Doctor have just arrived back after saving a planet. Shortly after putting the space/time machine in orbit around a moon of Poosh, he had asked Adric to help in repairing some of the circuits of the old box. Tegan and Nyssa decide to take this opportunity to prank the teen.
Once Adric and the Time Lord finish the repairs, he trudges back to his room. He opens the door, he doesn't immediately notice anything amiss. Only after he flops down on his bed, thumbing through the TARDIS's copy of Treasure Island does he spy it.
Rising off the mattress, the teen stalks over to the picture frame hanging from the wall. Normally, sitting in the frame is a photo of himself, and the previous face of the Doctor. It now holds a picture of Freddie Mercury,the lead singer of the band Queen. The boy looks at all the other photos that he keeps in his room. Finding in each of the frames a photo of Freddie Mercury.
Immediately, Adric knows who is behind this. The only other TARDIS occupants are Tegan, Nyssa, and the Doctor, and Adric was with the Time Lord all afternoon. So the only logical explanation is that it was Nyssa and Tegan. The teen vows to get the girls back in some way.
"Hey, Tegan, Nyssa," Adric says, standing in the doorway of one of the many TARDIS rooms the girls like to hang out in, "I just wanted to let you know that I made some brownies. I figured you'd like to know, help yourself."
"He made brownies? I almost feel bad for pranking him," the Australian says. The two girls make their way to he time/space machines kitchen. It takes them a few minutes to locate it in the maze of constantly rearranging halls.
Innocently sitting on the countertop is a baking pan, tin foil covering it. Peeling back the foil they find, not brownies, as they initially assumed, but E's cut from brown construction paper.
Leaning in the doorway is the smirking boy genius, "I did say brown-es." He runs off deeper into the TARDIS.
"Oh, it is on."
The Doctor had landed the TARDIS on a relatively calm planet, and has asked Adric to accompany him on a supply run. The boy, of course, agrees.
Nyssa has gone to the library to read. She figures she would take the opportunity of a rare reprieve from travelling to catch up on some reading.
Tegan takes the opportunity to set up some practical jokes. She enters Adric's room, bundles of sticky notes clasped firmly in her arms. Slowly, and meticulously covers every surface with the small, coloured paper squares. She double checks to confirm that every surface is covered.
Noticing that Nyssa isn't in her room, she decides to prank her as well. The Aussie fills a paper cup with water, balancing it on top of the door.
The Trakenite is the first to arrive back at her room. A copy of The Phantom of the Opera clutched in her hand. Pushing open the door, the cup falls from the door, drenching Nyssa's curls in water. She rolls her eyes, knowing that she has a plan on how to get Tegan back.
Later that day, the Doctor and Adric arrive back at the big, blue box. Both of the girls venture to the console room, helping to put the supplies where they belong. Returning to his room, after everything has been put away, he opens the door, finding every surface covered in small pieces of colourful paper.
Not knowing what else to do, he removes each note, throwing them into the trash can, which just so happens to be dimensionally transcendental.
Arriving back from the planet Zlcajur, Tegan takes the gems from the caves that the miners gave her to the TARDIS attic. The other companions of the Doctor decide to take advantage of her distraction.
Nyssa is the first to enter the Aussie's room. She makes quick work of turning the sink into an aquarium. After filling Tegan's shampoo bottle with baby oil, she leaves the bedroom, acting completely and totally casually, as she passes the Time Lord in the hall.
Only minutes later, Adric sneaks into the air-hostesses room, putting half-filled paper cups on the floor. He starts at the back wall, and lines the cups in straight lines, leaving just enough room for the door to open.
That evening, Tegan goes to enter her room. Pushing the door open, she finds, much to her disdain, hundreds of paper cups. Growling in feigned exasperation, she goes about cleaning up the cups. Deciding to just shower and go to bed, she finds a fish in her sink. Ignoring that for the moment, she just does what she set out to do.
The next morning, she wakes to find her hair far greasier than it was prior to washing it, she throws her shampoo away, knowing somebody did something to it. Bagging up the fish, she marches to the console room.
The Aussie finds, half under the console, the Doctor humming some tune. "Oh, Doctor," she calls.
From beneath the control unit, she hears a loud bang, and slowly sliding out is the Time Lord, rubbing his head. "Ah, Tegan, what can I do for you?"
The Australian holds the fish out to the Gallifreyan. "Does the TARDIS have an aquarium? Because I found this in my sink."
"Hmmmm... I wonder how that happened. I'll return this little guy to where he belongs, then." Standing up, he brushes off the knees of his trousers. He grabs the fish, and moves deeper into the time/spaceship.
"And he didn't even mention the hair."
Throughout the next few months, the pranks upsurge in quality and grandeur. Pictures of Nyssa's face covers every surface in her room. Everything in Adric's room is wrapped in tin foil. At times they would die down, but someone would go all out, bringing the jokes up to the higher level once again.
Somehow, through all of this, the Time Lord remains completely oblivious to these jokes.
Adric has just taped a ginormous sillohette of an insect to the inside of Tegan's lampshade. He leaves the room mere seconds before the Aussie returns. She turns on her light, and lets out an ear-splitting scream.
The Doctor comes racing for her immediately, trying to ascertain the cause of her scream. He enters the room, finding absolutely nothing. "Tegan, why are you screaming?"
The Aussie points to the lamp. Apprehensively, the Gallifreyan approaches the light, he reaches over to the other side of the lampshade. He plucks the piece of taped paper from the underside of the shade. "Okay, who put this here?"
Slowly, Adric approaches the door from one way, Nyssa from the other.
"Well, you see..." The teen begins.
"What happened was..." The Trakenite continues
"We've been having a sort of prank war." The Aussie finishes.
All three of the Doctor's companions begin a spiel about how the practical joke war started, the pranks that have been pulled since. The rambling stops when the Time Lord lifts his hand.
"I really don't care about the logistics of the pranks. Have your fun...as long as no one gets hurt."
A smile brightens each of the three faces. "You really mean that, Doctor?"
He nods his head, walking off, shaking his head at their antics.
The next morning puts a stop to the pranking when all three companions wake up with green hair. It seems the Doctor actually did mind the pranks. Needless to say, no more pranks are pulled on the TARDIS.
