Travelling the Interdimensional Space continuum with Emit Rellevart

Humpty Dumpling-eater, now satisfied that Sally was both firmly tied and silenced, returned to his chair, and sat down triumphantly.
"Now, you just stay there and be a good girl," he chuckled to himself as he took a mouthful of dumplings, "Not that you have a choice."
He took another mouthful of dumplings, and laughed through his teeth.
"It's only a matter of time now, until the Id TV lands in a dimension, and I can take over the…"
Humpty's monologue was abruptly cut short by the Id TV prematurely landing in a dimension.
"…world." Humpty finished.
"Ha ha! We have arrived. Now to put my plan into action!"
Leaping from the table, Humpty grabbed Sally's chair, and with strength surprising in an over-sized egg with arms, legs, and facial features, lifted the chair and Sally into the air and carried them from the room.The evil Dumpling-eater made his way quickly through the Id, apparently knowing exactly which corridors to take, and how far to travel down them, before changing to the next.
Sally, trying to remember where they were heading, was about to give up when they burst into a larger room, which seemed to all intents and purposes to be the Id's control room.

It was the Id's control room.Humpty quickly took a handy nearby rope, and tied Sally (and her chair) firmly to a handy nearby pillar.
Just as he finished, another door opened, and Emit walked into the room, clutching Renidt tightly in his hand. Obviously pleased to have captured the faulty device, Emit failed to notice the evil egg and his helpless hostage for a few moments.

Eventually, however, he did.
"What the?" he demanded.
Mildly unsure what Emit was asking with this question, Humpty ignored him and began to laugh nefariously: "Mwhahahaha!!!"
"Humpty Dumpling-eater, you fiend," Emit cried dramatically, "Let the girl go, its me you want!"
"Actually, Emit, it's not you or the girl I want," Humpty corrected, "I just want free access to this dimension, in order to take over the world!!!"
"You'll never get away with this, Humpty!" Emit announced.
In true villain fashion, Humpty stared at Emit, and, in a menacing voice, uttered those famous villain words: "I already have."
Just at that precise moment, another door flew open, and a large green evil-looking dragon-like creature, a young boy, and three sheep rushed into the room.

Grisly-vile, preparing to launch into a villainous soliloquy, paused when he saw Humpty standing there, already having completed one of his own, and was struck from behind by a sheep, which had slipped on the smooth Control room floor and was now a woolly projectile. Before he had time to utter "You'll never stop me," or "I am invincible," or even "Mwhahaha," Grisly-vile found himself lying on his back, staring up at the ceiling, with a dazed sheep lying nearby.

Humpty, still recovering from the shock of having Grisly-vile enter, and then get struck by a sheep, suddenly found himself the target of another sheep missile, and was soon lying on the floor next to Grisly-vile.

Now would have been the perfect time for Emit to recapture the two villains, except that the third sheep had struck him, and he was also lying on his back, albeit a small distance from the other two.

Dave, the only person neither tied up nor involved in the sheep missile crisis, stood just inside the door, looking upon the carnage before him, and wondering what to do.

His eyes were quickly drawn to the figure of Renidt. Now free of Emit's clutches, the small spherical golf-ball-without-the-spots-like object was quickly bouncing towards a ladder. At the top of the ladder Dave saw one of those porthole doors, like on submarines, which looked to Dave a lot like an exit (in fact, it had one of those green 'exit' signs beside it, which also suggested this).

Two thoughts simultaneously entered Dave's mind.
