Okay, you all have convinced me (and the low prices help). I'm getting DS the hex bug nano 3D elevation kit for Christmas. He's 4. How many hex bugs does he need? How many kits? Should I get the first hex bug hive, too? This will be his big gift from DH and me, I think, because the kid doesn't really need anything. Santa could get him some extra bugs. You tell me how many and how much or dissuade me, because he won't really love them.
