Tumfoid

Located only where Gelatonium was abundant, Tumfoids got crazed at the mere sight of the substance. While they were not aggressive toward Ratchet in any way, it was important to have correctly utilized his Gel Cubes when Tumfoids were nearby, as they immediatly started gnawing away at any Gel he shot. While they were not aggressive, Tumfoids cannot be killed. This doesn't mean for them to be ignored, as they were extremely annoying and had impacted on your plans.

Guide
The best way to have dealt with these Gel-hungry creatures was to give them their own cube to snack on, then quickly shoot another one or two cubes while they were distracted. Another great strategy was to simply shoot them with the Gel and they will have been stuck inside it for a short time or be knocked by you into rivers of gel inside the plants and drowned (so will Ratchet if you were not careful).

Trivia

 * When Ratchet asked the Smuggler why he had traveled to Sargasso, he said that he had trafficked Forssockers for the Kerchu, to have the Tumfoids scared. This must've meant if Ratchet had tamed the forssockers (but were never been seen by Ratchet as they were purely a mentioning), it would be the only way to permanently get rid of the Tumfoids, as they couldn't die.
