Plot
By Tidmouth Sheds, Biff looks at his harmonica as Emmett Brown shows up after hearing the awesome joke from The Thief. He recommended him to do the "Repairs Theme" from Thomas & Friends, but Biff can't play it. He does his own ditty and Emmett says it is a great song. Before he try to go see Mr. Kennedy, he gets run over by Johnny 5, who came back with his laser as his new mechanism which The Thief demonstrated to Biff. Afterwards, Johnny 5 pushed Emmett Brown away and Biff stated it was freaky.

Rainbow came by and asked that Biff saw the TP and Biff answered "duh". He recommended him to play "Sweet Victory" by David Glen Eisley and Bob Kulick, but he knew one song that SpongeBob SquarePants never sang it. He tried to, but that's his stupid question and played his ditty before Rainbow can learn how to play it. The Other Thief arrived on his shooting mech and Rainbow stated that he had medication and The Other Thief used his shooting mech to shoot him down and left. Babs pecked out the shed and Biff said that the movie is not about guitars and Babs closed the door.

Soon, Emmett zapped himself with an AA battery and Biff was furious that it was time to go home. Darth Vader arrives and asked Biff that he played the harmonica and cannot play one song something painful. He gave Darth Vader his harmonica and played his theme. Biff was very impatient after the song ended, he stated that it wasn't very good. Darth Vader asked him what he said and then pulled his light saber.
