Righteously mellow creatures featured in “Go With the Flow.”

• CRUSH, a 150-year-old sea turtle who knows how to hang loose, teaches Marlin a thing or two about being a good parent. Look for a strong singer who can confidently belt “Go With the Flow” to make it a truly radical jam.
• SQUIRT, offspring of Crush, fearlessly twirls through turbulent waters of the ocean and enjoys trying out cool new moves in the high- speed EAC.
• KAI and BREEZE each have individual singing solos in “Go With the Flow.”
