TWICE Sana narrated a gross childhood experience wherein she felt really grossed out and scared. In one of her appearances in JTBC's "Knowing Bros," she told an old life story while in Japan.

While everyone was guessing, Kang Ho Dong presumed that Sana was buying a bottle of water in a vending machine, but flooded with bottles of the drink instead. Although he is half-way into arriving at the correct answer, the KPOP idol said, it was not what it came out.

They continued the guessing-game until Sana gave a hint about what came out instead was unusual. One said its bug that was wrong until finally, Seo Jang Hoon got it correctly. Frogs were dispensed instead. Yay!

Sana said, "Lots of frogs were released!"

She explained that small baby frogs began coming out of the vending machines coin slot. She then discovered lots of them living under it.

When one of the hosts said that it might sound scary for a while, but it would not really feel like one afterwards. Heechul explained that if a number of it would come out, it would totally feel gross. He even joked that what if there are a 20 Hodongs in the set (parodying him). Everyone burst to laughter.

Feeling scared and gross at the scenario, instead of filling up her thirst, she just ran away with her mom to the car.
