I've been working on this pack for a while, but it's pretty done now. The reason why the terrain.png is still unchanged is because the graphics in the few pokemon games with 16x16 tiles look awful to me. If I would ever change the terrain, I would change a few plants, saplings etc. to look more like those in the 3rd gen games.

The mobs that are ready now are:

Golurk = Iron Golem
A rather fat mudkip = Pig
Marshtomp = Zombie Pigman

Typhlosion = Zombie
Treecko, evolving when tamed = Wolf
Rotom = Blaze
Koffing = Creeper
Ditto = Slime
Skeleton = Bisharp
Chicken = Torchick
Cow = Pikachu(request)
Sheep = MISSINGNO.
Squid = Magikarp
Enderman = Gallade
Magma Cube = Grimer
Ghast = Darmanitan
Silverfish = Weedle
Spider = Voltorb
Ocelot = Eevee
Cats = Eeveelutions(flareon, umbreon, espeon)
Villagers = Troh and Sawk
Cave spider = Shiny Voltorb
Mooshroom = Shiny, mushroomy pikachu

Items:
Raw Chicken = Torchick
Cooked Chicken = Combusken
Raw Fish = Wooper
Cooked Fish = Quagsire
Spawner eggs = Pokeballs
Chicken Eggs = Pokeballs
Leather armour = Pikachu fan suit
Raw Porkchop = Mudkip
Cooked Porkchop = Marshtomp

Variants:
Pig = Tepig
Zombie Pigman = Pignite
Sheep = Arceus
Enderman = Blaziken(request)

Many people are having problems with downloading, and I've been asked by many why. I dunno, but I've got a texture pack with the same mob files.(variant folder)

Additional Notes

-I'll make variants of the mobs if this gets popular enough, but first I need to find out what the undone mobs could be.

-This is not meant to make so much sense, but you'll love it because of that!

-If you've got problems downloading it, please let me know
