Every 100 Years

"There is a plant in the middle of a forest somewhere in The Wonderland. It is very modest-looking, almost like a weed, and therefore it doesn't attract much attention. However, there is more to it than meets the eye but only very few know its seacret.
Because once every 100 years at midnight it blooms and inside its biggest flower is a pearl. It is said that whoever sees this pearl, gets one wish that will come true. Have you seen it?"
