How to Evolve Sandile in Pokémon GO: Krokorok, Krookodile & 12km Eggs
Wondering how to evolve Sandile into Krokorok and Krookodile in Pokémon GO? Here is the complete roadmap covering Candy requirements, 12km Strange Egg hatch pools, and distance tracking methods.

Desert Crawlers: The Complete Sandile Evolution Guide in Pokémon GO
Originally introduced in Pokémon Black and White, Sandile remains one of the most sought-after hatches in Pokémon GO. Because the Desert Croc Pokémon rarely appears as a standard wild Overworld spawn, completing its evolutionary line requires deliberate planning and consistent walking distance.
Advancing Sandile through Krokorok to its final form, Krookodile, demands a sizable Candy reserve.
Below is the verified breakdown of all evolution prerequisites, how to secure 12km Strange Eggs from Team GO Rocket, and the fastest methods to stockpile species Candy.
Evolution Costs and Milestones
The Sandile family follows a traditional three-stage evolutionary path without requiring arbitrary secondary mini-games:

Evolution Path:
- Sandile to Krokorok: Requires 25 Sandile Candy.
- Krokorok to Krookodile: Requires 100 Sandile Candy.
- Total Investment: 125 Sandile Candy from initial hatch to final form.
No evolutionary stones like Sinnoh or Unova stones are needed, and you are not obligated to walk Sandile as an active companion to unlock the evolution prompt.
Where to Find Sandile: 12km Strange Eggs
The primary method to acquire Sandile is by defeating Team GO Rocket Leaders:
Strange Egg Acquisition:
- Defeat six Team GO Rocket Grunts to assemble a Rocket Radar.
- Equip the radar and engage a leader: Cliff, Sierra, or Arlo.
- Ensure you have an open egg slot prior to initiating the battle to secure a red 12km Strange Egg.
- Load the egg into a Super Incubator to reduce walking distance down to 8 kilometers.
Strategies to Accelerate Sandile Candy Farming
Hatching enough 12km eggs to amass 125 Candy takes substantial time. Accelerate your progress using these techniques:
- Set Sandile as Your Active Buddy: Walking your companion yields one Candy every 5 kilometers. Feeding your buddy a Poffin halves this distance down to 2.5 kilometers per Candy.
- Rare Candy Allocation: Allocate surplus Rare Candy earned from Tier 5 Raids and PvP reward tracks to bypass egg RNG.
- Transfer Multiplier Windows: Save duplicate hatches to transfer during dedicated Spotlight Hours offering double transfer Candy.
