In #thewizardofoz the Wizard gives #TheTinMan a heart that's similar to a pocket watch.

In the original #thewonderfulwizardofoz Oz gives #TheTinWoodman a heart made of silk and stuffed with sawdust and assures him that it's a tender one.

#TheTinMan getting buffed in the Emerald City in #TheWizardofOz is based on Chapter XIII of #TheWonderfulWizardofOz where the Winkie tinsmiths repair #TheTinWoodMan after his encounter with the Winged Monkeys.

It's #Worldbeeday? That doesn't bother #TheTinWoodman one bit
