The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necessary, capitalization should be fixed.

The Sarathos Swamp Jellyfish was a harmless creature that floated in and out on the oceans of Sarathos. It had a brown spherical head with what appeared to be extremely dark yellow or orange, spots around the spherical head and four tentacles under its body. The creature could be seen outside the Dreadzone course on Sarathos. Ratchet couldn't get any closer as it was too far out in the sea to reach.
