How is it possible?!

So probably a dumb question, but how in the blue hell is the Reliant Energy armadillo wearing a shirt with the shell still on its back? Does he remove the shell and then put the shirt on? If so, I thought shells were attached to them and were unremovable—how does it do it? If not, then how the hell did he get that shirt on in the first place??

I demand an answer or a discount for this if the only explanation is “because he’s fake.”
