Mechanics
Players can fish in Ponds to catch different types of fish for food or Biofuel.
After 10 minutes in-game or on Day 3, the 'Frog Invasion' begins, causing hostile Frogs to emerge from all Ponds.
Players can fish for Frog Keys from Ponds marked with a key icon, which are needed to access the Frog Cave.
A specific whirlpool pond appears on Day 3 or 4, which is the gateway to the Frog Cave dungeon.
Trivia
The Frog Invasion Update on August 22, 2025, fundamentally changed the function of Ponds in the game.
This update built directly upon the Fishing Update from August 15, 2025.
The launch of the Frog Invasion included a limited-time 'Update Party' event with gem rains and chaotic frog spawns.
Community guides recommend fishing within the first 10 minutes of a run to safely gather resources before the frogs appear.
