Don't Wake the Fish!

Don't Wake the Fish! is an underwater stealth idle game on Roblox developed by The Sleeping Giants, launched August 2025. Players swim through an aquatic environment, stealing sleeping fish before they wake and give chase - including an escalating shark-level threat. With 57 million visits, 1.29 million favorites, and a 93.1% approval rating from over 101,000 votes, it earned one of the strongest community receptions in the stealth-collection genre.

The core loop combines stealthy fish collection with offline income and milestone-based progression:

• ⚔️ Steal sleeping fish - approach fish quietly underwater and grab them while they slumber; if disturbed, they pursue you
• 🗺️ Shark threat - the shark represents an escalated danger tier when fish wake; outswimming it is the key survival skill
• 💰 Offline income - fish placed on your personal plot generate money passively even while you are logged out
• 💎 Progression milestones - earn milestone badges at $1,000, $100K, and $1M, culminating in the "The Legend!" endgame badge
• 🗺️ Coil upgrades - unlock the movement Coil for faster swimming, making both collection and escape more effective

The game features a seasonal ice variant (the winter [❄️] mode visible in the game title) and active development through April 2026 with four places including the main game and developer testing areas. The lean monetization model - just one gamepass (2x Money at 199 R$) - keeps the experience accessible.

For similar stealth collection gameplay with a meme-creature twist, Don't Wake the Brainrots! offers the same sneak-and-escape loop on land.
