This creature behaves much like the Hive. It is stationary and regularly fires out pink projectile worms, 9 at once. The worms squiggle rapidly through the air erratically all around the Yellow Sea Sponge. It looks like a dark yellow mass of soft tubes anchored to the floor. It pulsates and spawns the swarm of worms about every 4 seconds.
Corrupted Form Edit
The corrupted form of the Yellow Sea Sponge is similar to that of the corrupted Hive. After being corrupted, the sponge will become harmless and periodically spawn health that Trace can collect.
