If you’ve been chasing the elusive three-segment Dudunsparce in Pokémon GO, here’s a step-by-step guide to your best shot. It’s rare, it’s exciting, and there is no guaranteed trick — but smart play can help tilt the odds in your favor.
Dudunsparce is the new evolution of Dunsparce introduced in Pokémon GO. When you evolve a Dunsparce using candy, you may get one of two forms:
- The common Two-Segment Form
- The ultra-rare Three-Segment Form
The three-segment version carries the same typing, moves, and base stats as the two-segment version — the difference is purely visual and cosmetic.
In Pokémon GO, the probability of getting the three-segment form is only about 1% of evolutions. The two-segment form accounts for roughly 99%.
You cannot tell before evolving which form you’ll get; the evolve button always shows the two-segment silhouette.
So yes — you need luck. But you can improve your chances by preparing well.
When & Why It’s Easier During Events
Because the odds are so low, Niantic typically enables special events to help trainers:
- During the “Completely Normal” event (September 23–27, 2025), encounter rates for Dunsparce were boosted, making it easier to collect candy and perform multiple evolutions.
- The event also offered 2× catch candy for catching Pokémon, which accelerates your ability to evolve.
- Also, shiny odds for Dunsparce were increased, making it more compelling to hunt during the event.
If there is a future event, that window is your best chance: more spawns, more candy, more evolutions. Outside of events, catching enough Dunsparce is slower, and you’ll need patience.
Steps to Maximize Your Chance
Here is a practical plan to chase that 3-segment Dudunsparce:
- Catch many Dunsparce
You’ll need 50 Dunsparce Candy per evolution. The more you catch (especially during event windows), the more evolutions you can attempt. - Use berries and curve throws
While these don’t directly increase chance of three-segment, they help conserve resources and increase catch rate, so you can gather more Dunsparce and candy. - Evolve in batches
Doing many evolutions in a session increases your exposure to the 1% chance. Don’t stop after just one. - Track your results
Keep a tally: How many evolutions produced two segments vs three. You might see if luck streaks appear. - Prioritize high IV / shiny Dunsparce
Especially during an event, evolving shiny Dunsparce gives you a chance at a shiny Dudunsparce (both two-segment and three-segment). If your goal includes shiny, focus on shiny Dunsparce first.
Understanding the Odds & What You’ll Get
Here are key facts:
- The chance is fixed at ~1% for three-segment form when you evolve.
- The two forms share all stats (HP, attack, defense) and moves.
- Three-Segment has no gameplay advantage — it’s a collector’s prestige.
- Max CP for Dudunsparce (either form) is 3,097.
- The best moveset for damage is typically Rollout + Drill Run in raids or gym fights.
Also, if you eventually catch or evolve a three-segment Dudunsparce, its CP in raids or research encounters ranges depending on level and boost.
Tips & Common Pitfalls
- Don’t waste candy on evolutions unless you’re ready. Every 50 candies counts.
- Be patient. With 1% odds, it may take dozens or even hundreds of evolves to see one.
- Watch for events. Boosted spawn and candy events are prime time.
- Don’t fall for false methods. Some may claim certain times or methods raise your odds — none have been verified by the community.
- Trade & friends: While you can trade Pokémon, the form (two-segment or three-segment) will not change via trade. Evolve yourself to try for three-segment.
Should You Farm for It?
If you’re a collector or a “flex” hunter, yes — going for 3-segment is a fun goal. But if your priority is functionality, the two-segment Dudunsparce performs identically. Use your resources wisely: if candy and Stardust are limited, focus on things with real advantage.
Still, every trainer dreams of that rare form. Doing many evolutions during event windows and staying consistent gives you your best shot.
