In Bother-It's-Gone, the law enforcements are alerted to Jack and Christmas Pig's presence, but they find a hiding place where a compass leads them into the Wastes of the Unlamented, where the Land's ruler, the Loser who makes people lose things whose enlivened parts (souls) end up in the Land of the Lost, hunts the unlamented but the protagonists get away.

They are sent to a palace where they meet a king called Power who tries to turn Jack over to the Loser, who wants to eat a real person despite principles branding it as murder.

After being able to say a proper goodbye to DP, whose physical body was destroyed on the motorway, and being assured he and the angel are happy there, Jack wants to recover CP, who did not land on the Island with him.

Back in his living room and returned to his normal size, Jack's family, who noticed his disappearance, are relieved he is safe and Holly promises not to bully him again, believing his story about the Land of the Lost.
