The giantess and some of her friends all stand up and take you over to a cage that could only hold the biggest of beasts, it had blue plastic tops and bottoms, in between a mass of bars criss-crossed to make a huge wall. For the girls, the bars were horizontally spaced far enough that they could barely get a finger through, while beams running vertically were few and far between. A door was opened on top and you were unceremoniously dropped in.
The first thing to stick out was the mass of logs covering the ground, though in fact they were wood chips and not pieces of large trees. Each piece of wood was three feet long and was too heavy for you to even lift, though you could pull and push it around a bit. Over at the bars, they were plenty far apart for you whole arm and room for more, but it wasn't quite enough for the rest of you, as you did this, the girls hovered around watching, but then seemed to disappear.
Before you could continue the escape attempt, something shook the whole cage. Looking up, you saw a hamster, gerbal or some sort of rodent, but it was huge, its back reached the roof of the cage twenty feet overhead and seemed to be cramped in. It looked at you as food and would easily grind you into nothingness if the chance was given, which meant that escape had to speed up and so so very soon.
Running away, you broke out the shrink ray and tried to shrink the creature, but it was too big and too furry, your shots just seemed to move the fur and get broken up before reaching the skin and effecting the rest of it. If it couldn't get smaller, that meant you'd have to get bigger and then of course get out of there, immediately.
By this point you were backed into a corner, below you, you felt a network of holes from a drainage system of some sort, each hole was around the size of your big toe, or maybe a little bigger. The creature was now just a hands-reach away, so hurredly, you brought the ray to bare on yourself and pulled the trigger. A funny sensation filled you, but instead of everything getting smaller, it got bigger.
By the time it was done, one of those drainage holes was in front of you, fifteen feet across, a half-mile away a stack of wooden mass was about to tople over in your direction. Seconds ago, your foot had been on it, stabilizing it with your weight, but now your weight was absolutely nothing to it and not in any position to help. Before you jumped, you got a look at the rest of the environment, a single wood chip was 100ft. tall, where before it might have been five inches. Time to be smaller than a bug...
