SpongeBob, Jimmy, Timmy and B.O.B.'s friend, Roger, is invaded by the Rat King and the sewer rats.


SpongeBob, Jimmy, Timmy and B.O.B. are testing out a new defense grid when Roger the alligator comes to them asking for their help. The sewer rats are stealing his stuff and are taking everything in his home. SpongeBob, Jimmy, Timmy and B.O.B. decide that there is no way to help Roger, except for switching his mind with Timmy's. Jimmy has a gadget that does just that and they switch brains, giving Roger Timmy's psychopathedness. Timmy goes back to beat up the rats while inside Rogers body. Through a miscalculation by Jimmy, Timmy becomes even more violent while inside Roger's body and goes on a rampage through the village that carries on into the city. Roger, trapped in Timmy's body, really wants to help out but SpongeBob, Jimmy and B.O.B. tell him he just isn't cut out for this type of action. SpongeBob, Jimmy and B.O.B. try to trip Timmy and hold him but he is too strong. Roger helps out by singing because he remembers that it had put Timmy to sleep earlier. Timmy falls asleep to the song and SpongeBob, Jimmy and B.O.B. are able to switch the brains back and return everything to normal.
