shadow figured he 'd learn soon enough what wednesday was up to , whether he wanted to or not , and so he prowled the liquidation aisles , staring at the things for sale : boxes of coffee `` for use in airline filters only , '' teenage mutant ninja turtle toys and xena : warrior princess harem dolls , teddy bears that played patriotic tunes on the xylophone when plugged in , cans of processed meat , galoshes and sundry overshoes , marshmallows , bill clinton presidential wristwatches , artificial miniature christmas trees , salt and pepper shakers in the shapes of animals , body parts , fruit , and nuns , and , shadow 's favorite , a `` just add real carrot '' snowman kit with plastic coal eyes , a corncob pipe , and a plastic hat .
