You need the next room, which is returned by this method.

The whole point of the loop is to go to the first room and get the next 
room, go to this room and get the next room, go to this room and get the 
next room ...

When you use "send" as suggested, the structure becomes clearer:

next_room = @start
loop do
  puts "\n--------"
  next_room = send_next room
end
