I keep reading this thread title as "Do you like anime," but to answer the question in the OP. I have no idea. But I saw this commercial on Facebook yesterday that advertised this like sticky slime stuff you could roll around in your car to clean up the crumbs and stuff. But what cleans up the sticky slime ball? I mean, do you just keep buying slime balls to clean the previous slime ball? Almost seems like a Ponzi scheme. Like Bitcoins, except instead of useless digital currency you're left with a sticky ball of slime that graham cracker dust in it.
This question was never answered in the advertisement. Perhaps it is machine washable, or you're supposed to take it out and rinse it off with the garden hose..... don't use it in winter
