Morpha the Aquatic Mass is an optional boss found within the Sunken Sea.
Summoning[]
Morpha is found in the Sunken Sea approximately 700 tiles from The Core in an area covered with slime.
A Morpha the Aquatic Mass Scanner can be used to reveal their location on the map. A loud thumping sound can be heard and the screen will begin to shake when Morpha is nearby.
Once defeated Morpha can be re-summoned by placing a Giant Slime Summoning Idol on their rune, located below their original spawn point.
Behavior[]
At full health, Morpha will only begin attacking players within a 6 tile radius of them. Once damaged, this radius expands to 20 tiles.
Morpha attacks by quickly leaping towards the closest player, dealing damage where they land and leaving behind a patch of Ground Slippery Slime.
Additionally, Morpha instantly breaks any non-indestructible objects in their path, including walls. Any pits/liquids will be filled in with Beach Block ground.
Every 3–6 seconds Morpha will briefly pause and shoot 30 bubbles in random directions, which deal moderate damage.
If the player moves out of Morpha's range during combat, or Morpha travels more than 25 tiles from their rune, they will return to their rune to regenerate health (10% of their maximum every 5 seconds).
Once Morpha reaches 30% health they will become enraged and begin moving much faster.

Tips[]
- Due to the bubble attack range weapons are preferred, as being in melee range will cause the player to quickly get overwhelmed.
- Clearing out an area 5-10 blocks larger than the default arena, and using a Scarlet Hoe to quickly cultivate the ground and clear any Ground Slippery Slime will make the battle much easier.
- This will also prevent any other enemies from spawning during the fight. The most difficult part of fighting this boss is being too close to it, due to the bubbles and their lingering effect, so creating a larger arena to fight makes this battle far easier.
