My friend said it's a pineapple😂. I was like: what？？! Well, believe or not, I was trying to paint a cliff with 兰花（Could anyone tell me how to say it in English？) and a bunch of bamboos. But yeah after my friend's words, now there's a pineapple's shape stuck in my brain.
Thank you～～! I looked up that before but the dictionary showed the picture of the butterfly-like flowers, so I was confused. Now I get it😊
