Please help me finding this item (Cobweb Cocoon)

I recently got into Haypi Monster 3, and have been enjoying the game so far. One of my favorite monsters is Octomom; its combination of unique skills and traits make it useful both as a support and a DPS, and being a rare it takes minimal investment. However, while I would like to evolve my Octomom into a Octola for the extra stats and access to new abilities, I cannot find the evolution item, the cobweb cocoon. I initially assumed it would be in the rotating honor shops on the battlefield, but after what must have been hours of searching I never saw it once. Is it just rare, or is it somewhere else? In game, it just says “unknown location,” which isn’t very helpful. I know this forum isn’t very active, but I’m reaching out because I figure that SURELY someone more experienced in this game has seen one somewhere before and remembers where to find it. If you can help, it would be greatly appreciated. Thank you!

Hello fellow adventure, english is not my first language but I’ll try my best to give you more information. Sadly, the evolve item doesn’t exist in battlefield honor shops nor anywhere else in the game usually, because this evolve item is actually an holiday event item. Remember the Halloween event that just passed where you can buy resources and special items in the main castle tent? If u paid close attention you would see an item that evolves the elite ghost type pumpkin monster, which looks like a wilted leaf. For our spider friend is the same, it only comes out during certain holiday events just like how pumpkin monster’s evolve item came out this time. Unfortunately I do not remember which holiday it was, but I remember seeing it.

Hopefully this was helpful, I’d suggest joining the discord server, there’s a tons of guide and people chatting helping others out. Best of luck with your journey!
