Currently, there are no ways to warp to the west beach, water slides or cliffside pond. I personally think these are integral to the warp system for these reasons:
The west beach is the other location you can go to dig up treasure during the event, and there are no other warps on the southwest side of the map anyway.
The waterslide area deserves a warp location as again, there is no southeast (and barely any south in general) warps that are near the slides. Also, waterslides are cool.
All three other fishing areas have warps near or at them. Why not have one for the pond on the cliff?
I’ve made a quick map of where these warps could be below.
What are your thoughts?
