How do I evolve Gloom? Considering the Kanto native has two evolutions, that’s a very valid question, and neither is as straightforward as increasing its level. Instead, Gloom’s evolution into Vileplume or Bellossom requires one of two specific stones. So, allow us to tell you how to evolve Gloom so you can get yourself a couple of powerful stage three Pokémon.
In generation one, Oddish, Gloom, and Vileplume are grass Pokémon, as is Bellossom, though the original three double as poison Pokémon in later generations. With that in mind, it’s wise to learn about grass Pokémon weakness and poison Pokémon weakness to give you an edge in battle.
Here’s everything you need to know about Gloom’s evolution.
Who is Gloom?
Gloom is part of the OG Pokémon lineup, being just number 44 in the Pokédex, evolving from Oddish. An interesting thing about Gloom is that many people think it’s drooling when, really, it’s nectar that the creature uses to attract prey. For humans, while the ooze is sweet, it smells horrific, so you should keep your distance unless you’re one of the few who enjoys the smell.
Where can I catch Oddish?
Oddish is quite a common Pokémon to find. It tends to be an early-game creature, so a standard pokéball should suffice when you try to catch one. Speaking of which, this is where you can find Oddish in the Switch games:
- Let’s Go Pikachu – Viridian Forest, Route 1, Route 2, Route 12, Route 13, Route 14, Route 15, Route 21, Route 24, and Route 25
- Let’s Go Eevee – Oddish is exclusive to Let’s Go Pikachu, so you need to trade with another trainer
- Sword and Shield – East Lake Axewell, Dappled Grove, Motostoke Riverbank, Rolling Fields, Watchtower Ruins, Giant’s Cap, Hammerlocke Hills, and North Lake Miloch
- Brilliant Diamond and Shining Pearl – Routes 229, Route 230, and the Grand Underground (Grassland Cave, Riverbank Cave, Swampy Cave, Spacious Cave, Sunlit Cavern, Still-Water Cavern, and Bogsunk Cavern)
- Scarlet and Violet – you can get Oddish through the Terrarium in the coastal biome in the Indigo Disk DLC
How do I evolve Oddish?
Oddish evolves into Gloom at level 21. It’s as simple as that: no items, no stones, just simply battle with Oddish to speed up the leveling process. You can also opt to use a rare candy, should you be lucky enough to have the scarce item.
Where can I catch Gloom?
You don’t have to evolve Oddish if you want Gloom. You can catch the second stage ‘mon outright, and it normally doesn’t take anything more than a great ball to get the job done. Sometimes, an ordinary pokéball is sufficient, though it’s more difficult.
You can find this Gloom in the following places on Switch:
- Let’s Go Pikachu – Route 12, Route 13, Route 14, Route 15, and Route 21
- Let’s Go Eevee – Gloom is exclusive to Let’s Go Pikachu, so you need to trade with another trainer to get it
- Sword and Shield – Giant’s Mirror, Axew’s Eye, East Lake Axewell, North Lake Miloch, Giant’s Cap, Dappled Grove, Giant’s Cap, Hammerlocke Hills, and Motostoke Riverbank
- Brilliant Diamond and Shining Pearl – Route 224, Route 229, Route 230, and the Grand Underground (Spacious Cave, Grassland Cave, Swampy Cave, Riverbank Cave, Still-Water Cavern, Swampy Cave, Sunlit Cavern, and Bogsunk Cavern)
- Scarlet and Violet – you can get Oddish through the Terrarium in the coastal biome in the Indigo Disk DLC
How do I evolve Gloom into Vileplume?
Gloom needs a leaf stone to evolve into Vileplume, the same stone you have to use to get Leafeon, one of the Eevee evolutions. Luckily, it’s easy to get your hands on. Here’s how you can get one:
- Let’s Go Pikachu and Let’s Go Eevee – Route 2, Victory Road, and Celadon Department Store
- Sword and Shield – Turffield, Lake of Outrage, the Bridge Field Digging Duo, and as a poke job reward for tier III, IV, and IX
- Brilliant Diamond and Shining Pearl – Floaroma Forest and the Grand Underground
- Scarlet and Violet – Tagtree Thicket, Artazon, Delibird presents, Terra Raid Battles, and Wistful Fields (you need The Teal Mask expansion to access this area)
How do I evolve Gloom into Bellossom?
Give Gloom a sun stone to evolve it into Bellossom. Getting one isn’t too difficult, as like other items such as a fire stone and water stone, there are numerous ways to obtain one in each game:
- Sword and Shield – explore Dusty Bowl, see if a Pokémon with pickup ability collects one, try your luck with the Digging Duo in the Bridge Field, and catch a wild Solrock (it has a 5% chance of holding a sun stone)
- Brilliant Diamond and Shining Pearl – you can catch a wild Solrock (it has a 5% chance of holding a sun stone) or explore the Grand Underground
- Scarlet and Violet – you can find them in Area Zero, East Province (Area Three), West Province (Area One), Artazon, Porto Marinada auction, and Paradise Barrens (you need The Teal Mask expansion to access this area)
Before you get your hopes up, you can’t evolve Gloom into Bellossom in Let’s Go Pikachu and Let’s Go Eevee, as the gen 2 Pokémon isn’t part of the Kanto Pokédex.
Where can I catch Bellossom?
On Switch, you can find Bellossom in the wild in Sword and Shield, though just because you can
