How wierd! I know this sounds absolutely impossible but they couldn't have been in a crevice/lip of the lid could they? I've been amazed at where Emi can stuff her little self. She's not a corn but rather a milk but very similar in size and that little growing worm can get into the most amazing places and appear to have disappeared. Glad they are both back home safe and sound though. Crossing my fingers that the BRB will be found as well.
