Blu is beleived to be wired wrong from birth. Hes so energetic and adhd, he cant pay attention to anything. BUT if something moves in the slightest way he wants to chase it down and till he catches a fish. He is also used as a hunter for this reason. He loves to chase anything and everything that moves. This is why he cant be an explorer, hed spend too much time chasing his tail or the butterflies or even biting the air as the wind moves through.
