-Louie, The Liac's hat flower, Lila's flower arrangement

-Mr. Freeze radio and Glacia Glaze's compact

-Jack O'Shea's GOSSIP PHONE walkie and Catwoman's receiver in the leopard head bust bust

-Printer's Devil's book also used by Lydia Limpet and Bookworms glasses

Clock King talks back and forth to Second Hand (his device unknown), then used same or different device to speak to B/R inside that large hourglass, see above Robins head. I assume B/R voice is also heard? and its not just a speaker?
