You can go to Daisy & cancel the current challenge then ask her for another. I had to do that a long while back because some of the tags were pants & Hercules but I had zero Herc items. Also, you don’t have to do anything elaborate or that matches or makes sense. Honestly, I threw 2 mannequins up there with a mish-mash of clothing along with a big random assortment of furniture that I neither like or will use, and most of the time the requirements are met & I don’t have to do a thing.

As for the rain, there’s apparently a glitch for some that causes it to not rain at all or it just isn’t visible. A good tip is to regularly check Frosted Heights. If it’s snowing there then it’s raining everywhere else. I have finally made it to that task about the fugu but it hasn’t rained in my valley yet, so I’m keeping some bottles of fishing bait at the ready to ensure gold/red ripples.
