It might be useful to distract your plot bunnies early in your writing. Set them to reading something, anything, other than your notes and you’ll know that any suggestions they bring you have nothing to do with your present work. (This is especially true if you set them to reading works in other languages than the one in which you are writing.)
I’m starting to prepare for the start of NNWM 2015 and the bunnies have given me their promise.
My bunnies come from a nifty custom crochet shop owner who operates through Etsy. Her store name is Galarples and in addition to bunnies of various types, she had other critters available. Please see: https://www.etsy.com/shop/Galarples
