Travelling the Interdimensional Space continuum with Emit Rellevart

The Id TV was quite large inside, and didn't seem to line up with where they had just come from.
Whereas Dave and Sally had been standing on ground level, they now seemed to be on the top floor of a huge mansion, which spiraled down below them for floors.
Sally was the first to comment on this, exclaiming: "What the?"
"Welcome to my spacious abode" Emit said, smiling and gesturing to the immense area before them, "This is where I live, and travel about through the dimensions. It's not much, but it has to do until I can afford something better."

Beeping loudly now, Renidt suddenly leapt off Emit's hand and rolled off into the depths of the Id.
"Oh no, not again" Emit sighed.
"What's wrong?" Dave asked, by now having given up on figuring out the earlier statements, and determined not to be left out of the current events.
"The Renidt is malfunctioning" Emit groaned, "That's why I appeared before. I was supposed to be going to Dimension 226, not Dimension 748!"
"748?" Sally gasped, "How many dimensions are there?"
"Well, so far the Council of 1 have discovered two thousand, seven hundred and sixty three dimensions, but explorers are always finding more. Even I have discovered three myself," Emit smiled.
"What do you do for a living anyway, Mr… er, Rellevart?" Sally asked.
"I work for Interpol" the tall man responded.
"Interpol?" Dave asked, "Isn't that an international police agency in our dimension?"
"That's just what they tell the citizens of your dimension to keep them out of the know" Emit explained, "In reality, it is an inter-dimensional policing agency, so far established in over six hundred dimensions. At the moment, I am tracking a fearsome Gremblin from Dimension 51 named Mallorkan. He is wanted in seventeen dimensions for…"

Suddenly a loud exploding noise, like a jet back-firing, interrupted the conversation.
"Oh no," Emit groaned, "Renidt is at it again."
"What happened?" Dave and Sally asked together.
"We've just left your dimension, I don't know where we're headed. Sorry kids, but it looks like you're travelling with me for now. At least until I can get Renidt fixed."
"But, my parents are expecting me home for lunch" Sally said.
"Don't worry," Dave reassured her, "If you miss out, I'll give you my soup."

"We're going to have to hunt Renidt down again" Emit said, "If it manages to get out of the Id TV in the next dimension we could be trapped indefinitely."
"Wait, if it gets out?" Dave asked, "I thought it was just like a fancy remote control. How can it 'get out'?"
"Well, it is a fancy remote control" Emit explained, "Only, it's a little too fancy. It kind of has a mind of it's own. Actually, it's really good at telling jokes, when it's working properly."
"What's wrong with it?" Sally asked.
"I think it has Renidtitus," Emit sighed, "It stops a Renidt's circuits from functioning properly, kind of like someone going insane."
"Is it cureable?"
"Eventually," Emit said, "But we need to get it to the Id's control board, plug it in, and reboot it first. And that is going to be difficult unless we can catch it."
"Then what are we waiting for?" Dave exclaimed, "Let's go and find it!"
"Just be careful," Emit warned, "A faulty Renidt can cause all kinds of weird things to happen, especially while traveling between dimensions."
"Like what?" Sally asked.

Suddenly, three sheep appeared out of nowhere and skipped happily off into the depths of the Id.
"Like that" said Emit.
"Random" Dave stated.
