Missing Shaking Encounters in XY/SM/USUM & Name issue in SM/USUM

All of these encounter types are missing from XY in the API:

• https://bulbapedia.bulbagarden.net/wiki/Ambush_encounter#Introduced_in_X_and_Y

This is important because many pokemon are exclusively encountered this way.

I would model these by adding multiple new encounter methods. Bulbapedia lists these all as "ambush encounter", but then sub-divides them into types. I would only name them after the sub-divided types. This would be:

• Shaking Berry Tree
• Shaking Trash Can
• Bush Ambush
• Drop from Cave Ceiling
• Moving Dust Cloud (Bulbapedia has this as leaping out of ground, but it's not descriptive enough imo)
• Sky Ambush

Some of these encounters are modeled for Gen 7. For example, Chansey is included in USUM. However, for some reason, this is listed as "Bubble Spot", which is the Gen 5 water bubble spot. The rest of the encounter data for it is fine.

That being said, we are still missing some gen 7 encounters like this.

I would rename chansey/cottonees method to:

• Bush Ambush (previously described in my XY section)

A lot of these encounters appear to be in the API, but some are missing.

I couldn't find the one for Rattata Alola in SM Route 2, for example. So I'll have to go in detail and double check everything.

That being said, I think SM/USUMs ambush types mostly have crossover with XY. The only new methods I could see to add are:

• Sand Clouds (beach? Maybe combine with dust clouds)
• Rustling Trees (I think keep separate from the berry tree one, as that's a distinct thing in XY)
• Wimpod Chase (Wimpod is currently listed as "only one" which is really not correct.)
• Water Splash (Could actually use bubbling spot from BW)
• Invisible Kecleon Spots

As usual, I wouldn't bring something up without being willing to take it on myself, but I hope someone else is interested as well.

Start by auditing the API's encounter data for XY, SM, and USUM against the Bulbapedia ambush encounter information linked in the issue. Check existing Chansey, Cottonee, Alolan Rattata, Wimpod, and related encounter methods, then verify that missing methods and names are consistently represented. Done means the affected encounter data is complete and correctly named across these games.
