Rumbling Waters Blox Fruits: 3 Sea Beasts

Rumbling Waters is a sea event in the Third Sea that spawns three Sea Beasts at the same time, under heavy rain and the Haunted Halls music. Each Sea Beast's health depends on the number of players who triggered the event: the more players, the more resistant they are.

How to get it

Triggers randomly while sailing in the Third Sea at any Sea Danger Level from 1 to 6. It does not appear in the Second Sea. A downpour similar to the rain at Tiki Outpost announces the event, then the three Sea Beasts emerge from the water.

Rewards

150 Fragments per Sea Beast (450 total)
125,000 to 250,000 Beli per Sea Beast depending on your level (375,000 to 450,000 with 2x Money gamepass)
+1 level per Sea Beast (3 total)
Possible drops: Choppa, Top Hat

Tips and Tricks

Position yourself behind the Sea Beast you're attacking: the Deadly Showers from the other two will hit it instead and you'll take less damage.
Bomb can solo this event very easily by spamming its [C] in the center; Magma, Buddha, Dragon, Venom, or Mammoth also work very well. Preferably face them one at a time, or with multiple players.
Large AoE moves (like Dragon Trident's) hit multiple Sea Beasts at once and quickly charge your Race V4 bar; Shark Tooth Necklace, Shark Cape (from the Magnet event, over since 21 September 2026) or Leviathan Crown add more damage.

Our take

One of the best events to farm in the Third Sea: three Sea Beasts that are easy to chain in a group or solo with a good AoE fruit.
