I hate pretty much anything that makes noise.
The one thing that I hate the most is those books that have the buttons on them to make sound effects. My kids played with those things ALL the time when they were little.
ETA :
Easy way to store legos , we have one of those plastic stacked drawers, 5 : 3 small 2 large. the top one is for projects they are working on, the next 2 are for the smaller pieces, the bottom are for the larger pieces or projects that are too tall for the top drawer. And we have a separate snap closed craft box, like one used for beads or fishing stuff, with the dividers for the stuff like mini figs , wheels, axels , tires, specialty pieces , etc.
