Hats

The bunnies are bugging me to get offline so they can go hat shopping. They claim they all must have little hats to wear for gardening, and this headgear must be purchased immediately. Have you ever heard of such before? And of course they need hats with ear holes in them which I imagine won't be easy to find given those rabbits' ear sizes. Does anyone know how I can convince them to go looking for something else instead?
