Trade an endangered fish to the Island 3 NPC to receive Carrot Bait. You cannot buy it or gather it from the ground. Equip it and cast from Island 3 to summon Pufferfish.
Make the trade and prepare the Pufferfish summon
Answer first
Bring an endangered fish to the Island 3 NPC and complete the trade for Carrot Bait. Once you have it, equip the bait and cast from Island 3.
Skip the shops and ground search
Carrot Bait is neither purchasable nor forageable. This task is an exchange, so focus on obtaining the required endangered fish and taking it to the Island 3 NPC.
Use Carrot Bait for Pufferfish
Equip Carrot Bait before casting from Island 3. That action summons Pufferfish and starts the endgame boss task.
Continue the route
Open the Pufferfish walkthrough for the rolling attack, tested cover tactic, dropped tail, seagull risk, and final delivery. Use the Island 3 walkthrough when you want the entire trade-to-escape sequence on one page.
Summon Pufferfish and follow the boss task
