Fourgys Follys

She shrugged, looked over at the 3D display riding the whimpering desk, and said, “I think you're an hour early, from what they told me, but what the heck. You might as well go on in.” She grinned, “it might be safer in there.”
Fourgy knew that Mmhm was a gas giant, and the office would have gas leakage, so he put on a gas mask, knocked, then opened the door. It opened a hand width, something mewled like it needed help, and the door slammed back shut.
He looked at Nicole. She was frowning at the door and said, “I think there's a problem. Try again.” He nodded and tried again. Nope, it slammed shut again. This time he thrust his weight into it and forced the door wide open.
His mouth dropped open. The whole office was pulsating, a huge multi-colored, floor to ceiling, pulsing space. Huge masses of spots and lines and blotches came and faded and travelled about, bouncing off the walls and ceiling. When he poked it, some blotches started roaring, all together like a flock of deranged vacuum cleaners. His head jerked about as he studied it-them-whatever, then he nodded. It was all in a bag. Maybe two gas bags. One more blueish on top, and one more pink on the bottom. The bottom one was making strange noises that came and went in time with a series of vertical rainbow colored ripples. It reminded him of the ripples in an Organo booster rocket about to burst, you've probably seen such pictures, when it tries lift something too big. You would probably recognize some of the other noises, one just like a vacuum cleaner trying to eat a sock. Plus other noises, like the normal ones when gas bags scuffle about on office carpets, only with at least three kinds of mewling at the same time.
