I also agree that I'm not thrilled with the final prize. It seems a bit off to me in some way, can't really explain it more than that despite staring at it for quite some time, lol.
If the Mountain Flow is recycled, it must be from an older s8 game like Farm or Nightclub because it's definitely new to BS or RS and isn't ringing any immediate bells for me. It does remind me of the Water Pump Planter from the Gardener's Box, though - maybe that's what you're seeing too?
