Official Bio
"Bailey is the Marine Life Institute’s resident beluga whale who is convinced his biological sonar skills are on the fritz. The good news — or bad news, depending on who you ask — is that doctors at the MLI can’t seem to find anything wrong with him. Bailey’s flair for the dramatic never ceases to push his neighbor’s buttons: whale shark Destiny can’t seem to get through to him, no matter how hard she tries. Maybe he’ll listen to new friend Dory, who seems to be full of crazy ideas."
