Pretending tiny people are trying to run from one side to the other while the Giantess toys with them. Some will make it and be safe, many will not. I start gentle with them, picking them up when they get near the end and putting them back at the start, or brushing my hair over them to knock them over. I get a little tougher on them - blowing them and flicking them back with my nails. I get very rough with them, sometimes pulling their legs off so they can't run. I squashhh them in my fingers or smear them on the wall. I put them in my mouth or teeth to eat. I sit back and stretch out my legs, using my feet and toes to crush the runners. I do this for a few minutes then stand up between the walls, walking to step on them. I use my toe nail to flick them around and my big toe to smear them back along the ground.
