From the Super Mario Wiki
Rat Funks are blue-colored rodents that reside in Kero Sewers and the Forest Maze in Super Mario RPG: Legend of the Seven Stars. They are cowardly creatures, and will often run away from battle. Rat Funks are also extremely fast, allowing them to attack Mario's party members before they have time to react. Since these rodents are fairly weak, they tend to travel in numbers or with stronger monsters, including Hobgoblins. In battle, a Rat Funk attacks by slapping its tail at a party member. Their tails can also be used to poison their enemies. These rodents are relatives to the purple-colored Alley Rats.
One friendly Rat Funk who lives in Monstro Town guides Mario to his hometown when he is met in Land's End.
