Maitimo's friends get to stay out past their bedtimes when he is around because none of their parents want to tell them to stop playing with him, so when they seem to be actually getting tired it is his responsibility to declare that he is tired and going home.
He is not tired, so he takes the long way home and eavesdrops and doesn't notice anything strange at all before a large snake with a portal for a mouth eats him up.
