Catch a Fish Obby
5.0

Catch a Fish Obby is a chaotic collector raider set in a bright obby world full of Fish and Brainrot Fish characters. Build a money making base with your favorite sea creatures, sneak into rival bases to steal their fish, and protect your own tank from greedy bots and other players. It plays like a sequel in spirit to both Steal Brainrot Duel and Steal Car Duel, this time with slippery platforms, oxygen blue arenas, and a full rarity ladder of fish to unlock.

You can play solo or share the same device in 2 Player mode. Every fish you own generates coins while you move around the map. Use those coins to unlock stronger and rarer characters, then return to the obby track and steal more from everyone else.

How to Play?

  • Hit: F or Left Mouse
  • Sprint: Left Shift

Basic Loop:

  1. Run through the obby, collect and buy new fish characters for your base.
  2. Each fish generates coins over time according to its rarity tier.
  3. Spend coins on stronger fish or save for high end draws.
  4. Sneak into other bases and steal their best fish while defending your own!
  5. Use events and ticket machines to roll for Mythic and Omega fish.

Rarity system and characters:  Common → Uncommon → Deep → Oceanic → Exotic → Apex → Mythic → Omega

Catch a Fish Obby features 31 unlockable characters across eight classes.

Events, tickets and base defense:

  1. Ticket Rain: A timed event that drops tickets directly into the arena. Race across the obby, grab as many as you can and avoid getting knocked off by rivals.
  2. Parachute Surprise Drop: A crate falls into the map with a random fish inside. Reach it first, defeat anyone trying to contest it and you can instantly gain a new character without paying coins.

What is the goal in Catch a Fish Obby?

Your goal is to build the strongest fish base on the map. Collect fish to increase passive income, upgrade into higher rarity tiers, steal from others and keep your own collection safe. The player who manages their income, raids and defense best wins the long game.

How is this related to Steal Brainrot Duel and Steal Car Duel?

Catch a Fish Obby continues the same buy and steal formula from Steal Brainrot Duel and Steal Car Duel but moves the action into an obby style arena with fish instead of brainrots or cars. If you already understand the loop in those games, you will feel at home here.

Can bots steal my fish?

Yes. Bots and other players can raid your base and take your fish if you do not protect them. Keep the most valuable fish deeper in your base, close doors when you leave and return often to push intruders out.

Is there any advantage to staying in lower rarity tiers?

Common and Uncommon fish are cheaper and good for early snowballing income. Once you have a strong economy, you can replace them with Deep, Oceanic and higher. Many players keep a few lower tier fish as filler while saving for their next Mythic or Omega draw.

Can I play on mobile?

Yes. Catch a Fish Obby supports touch controls. Movement, jump, attack, buy and steal actions are mapped to on screen buttons so you can play comfortably without a keyboard.
