These events where you get a diamond box exclusive are starting to annoy me. Yay, new emoji, but wait, you only have a 10% chance of getting it after you grind through an event, but, as a bonus, there may be an insanely hard Rainbow Falls, which gives you another chance at that 10%. I'm starting to tune out of the events, and just concentrate on leveling and buying normal emojis, because the events are worth less to me in terms of time and interest.
I'll do it, because I can use some emojis that generate a lot of coins while looking for the items, but I honestly don't think I'll get anything out of it other than another Snowman.
