I didn't have any more bananas, but she was a good sport about it and even let me shake her trunk! (But that was probably only because her trainer held his stick up in the air and she knew she'd get a gentle whack in the head if she tried to get rough and sniffy with me.)
I totally broke my bunch of bananas in two because I wanted to experience the weirdness of feeling her sniff around my hand and then grab the bananas twice!
