Recently, a troublemaking crow has appeared on Third Street. After suffering from its tricks, Tama and the others are joined by Bull, who has also had a hard time because of it, and they decide to stand against it to teach it a lesson. After a fierce scuffle, Bull takes off after it, but what he finds at the end of the chase is...

Bull is the berserker of Third Street! But lately, it's been noticed that he isn't really a bully deep down. Tama and the others aren't afraid of him anymore. As Bull frets over things not going his way, he comes across a sneak thief's mask. Bull puts it on and appears before the others, declaring himself "Masked Bull." What will Tama and the others do?
That crow seems like even 
more of a glutton than Tora!
!يبدو ذلك الغراب شرها أكثر من تورا
Diese Krähe ist wohl noch
gieriger als Tora, was?
Ese cuervo debe comer más que Tora.
Ce corbeau est plus gourmand
que Tora ?
Quel corvo sembra un mangione peggiore di Tora!
Esse corvo não é mais guloso que o Tora?
Кажется, эта ворона
ещё большая обжора, чем Тора!
