Here's a Sing headcanon
Buster’s illegal activities (mainly draining the water tower from another building) catches up to him and, due to association, Meena. Nana gets them the best lawyers money can buy, but facts are facts. They committed a crime, and both are sentenced to jail time (I don’t know how likely that is, but hear me out). They get to the joint, and tiny, fluffy Moon and large-but-timid Meena don’t look like they’re gonna last the day in lockup. They’re approached by a large, menacing gorilla. “You’re Moon, own that theater?”
“And you’re the elephant with the angel voice?”
A stammered yes, thank you.
“I’m Johnny’s dad, and I owe my son’s happiness to you two. Don’t you worry about a thing in here. You two are with me, and anyone that messes with you has to answer to me and my crew.”
Suddenly jail seems more tolerable.
