my darking children are about to make all my nightmares come true; i put alot of work into the garden and the worst thing i can imagine is this:

so they have persuaded their mother to buy them one of these: http://www.twenga.co.uk/dir-Toys-Games,Outdoor-games,Water-Trampoline some hideous sort of water trampoline of pool and trampoline contraption, in all honesty i dont understand it and this is what it most looks like on the box...
how do i stop the grass dying? i know i need to move it around alot but how often? every day? every week? and should i be compensating by giving a little extra fertiliser or seed every now and then? i hope someone has the answer
