I tried on the first day and it was 1/3 and I have seen X post that it is less than that [an example:https://x.com/JydFOPt2D2Ic3ox/status/1898692412949889041]. I am not motivated to use tickets for giant mushrooms, which often use them, and the colors are random.
At the very least, if the current setup is what the management intends, I will give up on getting the White Day deco once and for all and will not try the new green mushrooms.
