That was the joke. For April fools, the joke was that the characters were such cradle fanatics they turned into a cult, a boat cult where they become boats and sail the open sea with Monica, the founder of the cult, being the mother ship.
@Eonlars
Mother was more of a term for cult leader. She's the "mother" of the cult.
President... There's probably a naval oriented association so the captain of The Lady got up to being the president and manager of all the boats in the harbor.
