In the live animal room, which was packed with people, they had tanks of cockroaches (those giant hissing ones), and the handlers would take them out to show people. At one point, while I was mere feet away from one such tank, out of the corner of my eye I saw a handler
drop one.
(Not far - just onto the table below.) And I
also noticed that it had wings! Hahahaha
Fortunately, they scooped it up immediately and no mass panic ensued, but that was when I decided to take my leave of the insect room.
