The SERP P*kemon mods adds over a dozen evolvable pokemons with PCs, Healing Stations, a currency system, and more. It also adds new mobs, bosses, and Team Rocket members, so watch out!
The full roster of P*kemons are: Bulbasaur, Charmander, Charizard, Squirtle, Caterpie, Weedle, Kakuna, Beedrill, Pidgey, Rattata, Spearow, Ekans, Pikachu, Sandshrew, Nidoran, Clefairy, Vulpix, Jigglypuff, Zubat, Oddish, Paras, Venonat, Diglett, Meowth, Psyduck, Slowpoke, Shellder, Cubone, Goldeen, Magikarp, Eevee, Lapras, Omanyte (through personal lab), Kabuto (through personal lab), Articuno, Shadow mewtwo (unobtainable in survival)
Catching Pokemon can be done by interacting with them with a pokeball, releasing them, and using the corresponding pokeball to tame them. Stars will appear when they are tamed.
Team Rocket members drop a combat insignia which can be traded for a VS Seeker, needed for multiplayer combat and helpful for seeking battles in general. The previously unemployed villagers now give these trades.
Use the combat insignia by simply interacting with it on your trained pokemon.
Berry trees give ingredients for rare candy as well as different types of potions. A bowl of rare candy can be used to instantly evolve a p*kemon, if it still has stages to evolve. They can grow faster with mulch.
Apricorn trees grow apricorns, which are used to make pokeballs. All trees can be cut with axes.
Personal Laboratories can used with fossils to revive/unlock new p*kemon. However, there is a chance of failure (15%) so you should bring multiple fossils.
A PC allows you to buy/sell items. Many items can only be obtained through the PC. A slot machine takes your money and gives you random items back. Both can be crafted in survival.
A healing machine can be used to heal your p*kemon for 1 coin each, and to interact with it you need a trainer card, which is bought from the PC store.
A storage PC can be used with the trainer card to hold p*kemons.
Mega Evolution starts with finding a pink mega shard, cooking it into an evolution fragment, which is then crafted into the sigil an the ring.
Pokeride can be used to saddle and fly pokemon with flight.
Rare mineral crates can be found in caves.
Last but not least is the Pokestop, which spawns around the map When you open it, bubbles will form. Pop the bubbles to get all sorts of good items.
