TL;DR
- Walking evolutions require specific distance milestones plus candy costs
- Eevee evolves into Espeon (day) or Umbreon (night) after 10km walked
- Baby Pokemon like Bonsly and Happiny need 15-25km as your buddy
- Always verify evolution requirements before using candy to avoid mistakes
- Optimize your walking strategy by combining multiple evolution goals
Pokemon Go introduces a unique evolution system where certain species require physical activity alongside traditional candy costs. Unlike standard evolutions that only demand candy accumulation, these special transformations integrate the buddy system directly into the evolution process.
Most Pokemon throughout the game world evolve through candy expenditure alone, with requirements ranging from 50 to 400 candies depending on the species. However, walking evolutions present a distinct mechanic where candy alone proves insufficient for transformation.
These particular Pokemon species can only achieve their more powerful evolved states after accompanying trainers for predetermined distance thresholds. Designate one of these special creatures as your in-game Buddy before embarking on walks or runs, and you’ll soon unlock powerful new battle companions.
The walking evolution system tracks distance through GPS and step counting, requiring consistent movement rather than simple candy hoarding. This mechanic encourages active gameplay while providing tangible rewards for physical activity.
Eevee represents one of Pokemon Go’s most versatile evolution candidates, capable of transforming into eight different forms. Among these possibilities, only Espeon and Umbreon require the walking evolution mechanic, making them distinct from their candy-only counterparts.
Both Espeon and Umbreon evolutions mandate that Eevee accompanies you as your Buddy Pokemon for a total of 10 kilometers. Additionally, you’ll need to accumulate 25 Eevee Candies to complete the transformation process once the distance requirement is satisfied.
The critical differentiator between these two evolutions lies in temporal conditions. To obtain Espeon, the Psychic-type evolution, you must initiate the evolution process during daylight hours. Conversely, aspiring Umbreon trainers should wait until nighttime conditions prevail before expending their Eevee Candies.
Pro Tip: Verify your game’s day/night cycle matches real-world conditions and ensure Eevee remains your active buddy during evolution to prevent failed transformations.
Baby Pokemon represent a special category of pre-evolved forms that initially hatch from Pokemon Eggs. These diminutive creatures including Bonsly, Happiny, and Mime Jr. all mature into their adult forms exclusively through the buddy walking system.
The specific requirements for evolving these Baby Pokemon into their mature counterparts are as follows:
- Bonsly to Sudowoodo: Designate Bonsly as your Buddy Pokemon, complete 15 kilometers of walking, then expend 50 Sudowoodo Candies
- Happiny to Chansey: Assign Happiny as your active Buddy Pokemon, accumulate 25 kilometers of walking distance, and subsequently use 25 Chansey Candies
- Mime Jr. to Mr. Mime: Set Mime Jr. as your Buddy Pokemon, walk 15 kilometers total, then utilize 50 Mr. Mime Candies
Strategic Insight: Happiny demands the longest walking distance at 25km, making it the most time-intensive Baby Pokemon evolution. Plan accordingly if you’re working toward multiple evolution goals simultaneously.
Optimizing your walking evolution strategy requires understanding several advanced mechanics. The game tracks distance in segments, updating approximately every 4-5 minutes, so sudden stops and starts may delay progress tracking.
Common Mistakes to Avoid:
- Evolving Eevee without proper day/night cycle alignment
- Attempting evolution without the required walking distance completed
- Switching buddies mid-progress and losing accumulated distance
- Forgetting to maintain the Pokemon as your active buddy during evolution
Efficiency Optimization: Combine multiple walking evolution goals by focusing on species with similar distance requirements. For example, work on Bonsly and Mime Jr. simultaneously since both require 15km. Check out our Class Guide for similar strategic approaches to game optimization.
