Can someone give me the name of a specific Spongebob episode?!

it's the one where spongebob loses his memory and gets attacked by the gang who snaps and they are after him because he blew the bubbles!. he then becomes mayor because he fought the gang and now the town can blow bubbles once again!.
i know its a very random question, but its a school assignment, no matter how crazy that sounds!.
thanx!!!! :)Www@Enter-QA@Com
