By far one of my least favorite event - actually I was wondering if digging into sand was worse than combining ingredients, still not decided but I tend to ''vote'' for current one. Reasons below:
The main prize itself: 1% pet food it's a bad joke. And seeing you can have the second base it's the next bad joke. At this % of pet food it does not worth even to evolve 1 to level 10. The pet food is the only important trigger to have it fully evolved and they decided to make it 1%.
Make it 50% and then, INNO, you will have a successful event and yes, players will try to get 2 fully evolved buildings. The pet food is the only important trigger to have it. Everything else we can obtain or already have from AW, MA, etc.
If nothing changes, on my live server will not attend this event. Does not worth.
The event mechanics: awful. Confusing icons, ridiculous requests for 1 or 2 points, really awful.
The daily hats: again, a bad joke given the prizes, chefs requests and the main building rewards.
