DD1 got the growth of a thousand children feature lol. There must be lots of tiny kids out there that missed out.
DS and DD2 got the ultra-magnetic dirt feature. I see messy kids out and about, but mine, no matter how clean they might have been thirty seconds ago, can be guaranteed to be filthy...it's embarrassing sometimes.
The gir;s also got the super human ability to eat - like teenage boys I swear....
