I tried this in very strange way, making a net that catches the cells.
'The net' is consists of Gluocyte and Keratincyte, it sticks into any cells and grows.
But after a while, the 'catched' photocyte will die (because they can't grow big enough to reproduce themselves while they are stick to gluocyte)
And the ecosystem will broke down. (But it will last enough to make challenge cleared)
