A little comparison of the previous updates.
Thanksgiving: All you really need to do is destroy the turkeys. You get a hat and a dagger. Melee is dropped I think. Turkeys have moderately low hp. Make take some time.
St. Patricks: Very laggy. Big crowd. Easy to grab coins. It's a matter of how good your luck is and if you're good at finding stuff.
Easter: Killing enemies isn't the case here. But killing players may happen. It's rapidly grabbing near the bunny and hope it drops an egg in front of you. Easy alone. But annoying in huge crowds.
Crab update: Something everyone seems to be annoyed about. Even on the first day. It doesn't matter if you dig one up or you kill it. Getting the melee is a small chance. The king doesn't always drop the melee and even if he does, you have like..... about 1 of 10 chance of picking up the melee due to the crowd. The high hp of the crab makes it longer which will attract more people like a magnet. Digging in an unsafe spot? Good luck with that! You get a cookie if you manage get one in a crowded pk area. Not to mention that there are I think.... 5 colours. You have 1 in 5 chance of getting the colour you want. Even lower chance. The only easy thing in this update here is getting the hat. Which is just killing the king crab.
