Pill bugs, or as they're better known as, "roly polys," are those ball-like bugs that you remember finding under a rock as a kid. Add a few around the house and watch people's expressions on their face when they visit. Have one crawling out from behind your couch, peeking around the corner in a bathroom or in a play area. Kids who like to collect all types of bugs and insects or aren't squeamish about holding bugs will also definitely want them as part of their room's décor. Depending on the color you select, you can opt for a realistic grey or brown one or have fun and make your pill bug orange.
