the fathers are extremely faithful, for example, if a father has his wife and all his babies eaten except one, and his only son is taken by scuba diving dentists, he will chase after his only son all the way into sydney fighting off sharks, lantern fish, and jellyfish. the dad will work extra hard if his son has a bad fin and will make many glib remarks if accompanied by an annoying forgetful fish voiced by Ellen Degeneres.
other than that... sorry i can't help...
