Batu Malang and The Bulb

Some days ago I was surprised by some questions.
"Have you ever come to Batu and Malang?"
"Sure, I have. Why?"
"Really? What did you do there?"
"Having fun, of course, spending my time with my family and friends."
"But, I don't catch that!"
"Catching what?"
"Your face. It shows that you have never been there."

It was really really disturbing me. Why? Because it was as if I never go there before whereas I'm a citizen of this province, East Java. And about my face, oh my Gooooooddddd!!! What's wrong with my face? Any trouble? Someone who asked me like this made me feel freaky. Made me feel freeze, windy, snowy, flowery and rainy. *Are they some expressions of feeling or some seasons?*

"So, any trouble with my face?"
I was just like a doctor in Sherlock Holmes serial, named Dr. Watson, whom always asked and asked when Holmes knew everything about himself and no one told him.

"No, it's just mmmm... your face makes me remember something named bentul, one of the special gift of Batu Malang which has a shape of a bulb that you can find at Dewi Sri traditional market in Batu Malang."
"WHATTTT????"

"That's right. Your face is like the bulb: simple but special!"

Ow-Em-Geeee!!!
Was speechless when he said that. But something I should know is, "How much does the bulb cost?"
Hehehe...
