Unrelenting whispers in the wind
Boba's favorite hobby is standing perfectly still whenever the wind blows. After a bizarre fishing accident, Boba's hearing has been left permanently impaired, which combined with a strong belief in the supernatural, has led Boba to believe that the sound of the wind whistling through leaves and grass are actually spirits trying to converse with him. All the other wolves have given up on trying to convince him otherwise, in no small part due to the fact that you typically need to repeat yourself to him 3 times before he finally thinks he understood you. Which, of course, he didn't.
Fílos found Boba one day as he was exploring the desert, and almost bumped into him because he was standing so still. Fílos found himself awestruck by the mysterious wolf, and was able to convince Boba (through no small amount of repeating himself) to join the Tomato Gang as a breeding male.
