Clayface Gets Dirty! New Robin & Clayface Two-Pack Comes with Slime!
New images of Clayface show it will come with a slime container like the Lazarus Pit’s Ooze. That explains what the trapdoor on his head, and action button are for. You will load the slime into his head, and press the red button to release Clayface clay-slime all over Robin.
Images of this new Clayface set and the new 2019 Joker Jaff Factory were found on Target.com, meaning we should see these released across the US.
