Waterdrops can be collected from the waterfall in the Fantasy Island. What I think you are actually looking for to open the Fantasy Island is the Dream Jewel in the shape of a drop. You can get those from the steeplechases (milestone rewards during events), from the Cloud race (for Constellation horses only) and from the Horse Wrangler by exchanging three food items every 12 hours.

Edit: Added a page for Dream Jewels, might be helpful for you :)
