There are 64 Kerotan Frog Locations in Metal Gear Solid 3 Delta Snake Eater (2025 Remake). Collecting all Kerotans unlocks the trophy/achievement It Ain’t Easy Being Green and the Stealth Camo. Kerotans are green rubber frogs. They are hidden in the same areas that contain the 64 Ga-Kos (yellow ducks). You must shoot them with any gun, then they make a sound and count as collected.
This guide is updated for the 2025 Delta Remake of MGS3 on PS5, Xbox Series X/S & PC. The Kerotans were also in previous game versions and are still in the same places. The ones you already found will get marked on the map. In the pause menu it shows how many you found total.
All collectibles are missable in MGS3 Delta. There is no chapter select. However, you can work around this by keeping a manual save every 2-3 areas. There are 31 manual save slots and roughly 70 areas. If you missed something you can load the nearest save and collect it from there. This allows you to use manual saves like a chapter select. Progress also carries over between playthroughs.
It’s highly recommended to go for all collectibles on Very Easy difficulty. This gives you access to the EZ Gun with infinite ammo, which allows you to stun enemies in 1 hit. You can combine this with the “no kills” playthrough.
To get all collectible types and trophies in one playthrough, follow our chronological guide by area:

/ 
. Take out the guards that search the area (non-lethally if on no kills run). If EVA’s stamina runs out she will refuse to continue walking, then must find food around the area and feed it to her from the food menu (keep your Tsuchinoko though).
