Any Grass/Ground/Water ‘mons you’re not seeing more of?

Let Wingul stay dead.

Where the F is Tangela?! None in the Kanto Event. None for Earthday Week. Maybe 4 from resesrch ... All junk. Gen 4 is right around the corner. Shes the main one im missing!

Geodude?

Trapinch/Mudkip, damn Flygon/Swampert.

Ones that are usually common barely spawn now: Bellsprout, Geodude, Roselia.
None of the starter Water or Grass types that I saw (Bulba, Squirtle, Treecko, Mudkip, Chikorita, Totodile)
No more Exeggcutes.
No Chinchous.
Not a single Sunkern.
Haven't seen a single Lileep or Trapinch either.

Tangela, haven't seen one ever in the wild after 2 years playing this game

To be honest, i see only few od each types during this event.

Water: Wailmer, Karp, Poliwag, Remoraid a lot, Carvanha, Corphist commonly and sometimes Feebas. Rest are rarely.

Grass: Seedot, Hoppip, Oddish a lot. Cacnea and Shroomish less. Rest rarely.

Ground: Rhyhorns,( normally i rarely see them) Diglets and Sandshrew. Noticed also some Larvitars. Before i caught just 1 in wild. Rest are random ocassionally.

I haven't seen more of exeggcute for this event that I want more of.

Granted there was a lot during the kanto event but I just need a tiny bit more candy to max my 3rd exeggutor

Was hoping to see a few Trapinch but I've still yet to see one in the wild ever.

In addition to the others already named, I'll give you another which I haven't seen at all during the event even though it is water/ground: Barboach.

I probably only noticed this because I only needed to catch one more of these to evolve it, and figured I would see plenty during the event (like with wailmer).

This has basically been a Magikarp and Wailmer event for my area. They are absolutely everywhere. But I'm certainly not complaining because I'm now only 4 big karp away from that stupid gold medal, and everyone in my area is on a frantic shiny whale hunt.

I haven't noticed an increased spawn rate of anything else I don't normally see. But I have seen 3 wild Larvitar, though. The first I've ever seen in the wild outside of one I saw on vacation during Adventure week last year.

no treeko, no mudskip

Clearly Niantic isn't just hitting a button that increases ALL pokemon of a certain type. They create a list of "event pokemon" that get a boost. This was proven when Slugma was part of the rock event and absent on the fire event. And there were whispers that Dratini was part of the water event back in 2017, but I never saw proof of it. Houndour was absent from the dog event but that event was clearly just an event list anyway.
