Where new codes appear
The developer's channels.
Official Discord — new codes drop here at updates and milestones: discord.com/invite/f965Yvk9DR
The game historically released its first code batch around August 22, 2026, and codes have accompanied updates since (the August 28 update added the Cthulhu code). There is no official Trello board, and the Roblox description doesn't list codes.
We re-check every code on this page after each game update and record the date — we don't write "updated today" without actually checking.
Codes FAQ
What are the active +1 Drain Water Per Click codes?
As of August 29, 2026, CTHULHU is the newest reported working code and rewards 1 Fish and 1 Cthulhu Ticket. It joined ADMINAQUARIUM, WATERHAPPY, and MYTHICFISH.
Why do guides disagree about code rewards?
The developer hasn't published an official reward list, so each guide site describes rewards from its own testing — and they word them differently (e.g. WaterHappy is called a Shark, a Random Rare Pet, or '20,000 Water and an Epic Pet'). We show the most-corroborated reward per code and flag the conflicts instead of picking one story.
Why does my code say invalid?
Codes are case-sensitive — copy-paste them exactly. If a brand-new code fails, rejoin the game to land on an updated server. If it still fails, the code has probably expired; codes have no published expiry dates.
How do I get new codes first?
New codes are posted on the game's official Discord (invite linked below) when updates or like-milestones hit. There is no official Trello and the Roblox page description doesn't list codes.
