Need help for Death on the Nile

[KennF]

In "Death on the Nile" in the Bar you are supposed to put 3 ducks "in a row".  I've found the ducks... what does "in a row" mean?  What exactly must I do?

Thanks for help!

Just line the ducks up on the shelf that is upper center between the two wooden ducks that are there.  I'm having trouble with the "complete rainbow" in Tim Allerton's room.  I found the pieces but can't find where to put them.  The don't go in the dart board.
