As you know, Frog Keys in 99 Nights in the Forest are dropped by Frogs, which are hostile creatures that appear next to ponds and other water bodies. When you kill the blue or purple frogs or fish from ponds, you may obtain a Frog Key, but what exactly do you do with this item? This guide will explain how to make the most of it.
How to Use the Frog Key in 99 Nights in the Forest
You need to collect 8 Frog Keys to unlock the Frog Cave event. In short, the Frog Key is a”gate-key” that lets you enter the special Frog Cave event area, where you fight waves of frogs and get loot.
| Step | Action | Tips |
| 1 | Collect Frog Keys | Kill frogs (especially Blue or Purple ones) or fish in ponds/lakes. The drop is not guaranteed; it’s a chance. |
| 2 | Accumulate 8 keys | You must have all 8 before you can unlock the cave. |
| 3 | Find the Whirlpool at Frog Pond | Once you have 8 keys, locate the Whirlpool in a frog pond. |
| 4 | Jump into the Whirlpool (enter cave) | Jumping in teleports you into the Frog Cave entrance. |
| 5 | Fight wave after wave of frogs | Inside the cave, frogs attack in waves, defending the frog chest. |
| 6 | Defeat the Frog King (boss) | The Frog King spawns as the boss in the cave. |
| 7 | Open the Frog Chest | After defeating the boss, the Frog Chest unlocks. |
| 8 | Claim the loot | The chest gives you one of several possible items, such as Poison Spear, Poison Armor, Blowdart, or Frog Boots. Also, you can fish inside the Frog Cave for a chance to get those same items |
Here are some things to keep in mind while fighting the frogs behind the gate:
- Use ranged weapons if possible when fighting frogs, since they can poison you using their tongue attack.
- Because keys drop only by chance, be prepared to spend extra time fighting frogs or fishing.
- In the cave, make sure to manage the frog waves efficiently and play with another teammate if possible.
- The loot is worth it, especially if you get Poison Armor or Frog Boots, which can work well with frog-area fights (or other poison mechanics).
