The Shadow Man from "Farewell, my Friend"

In Rugrats Episode called "Farewell, my Friend", 

Chuckie's Dad, Chaz who wear a Coat, a Gas Mask and some Gloves  

came out of the Greenhouse and then Tommy, Chuckie, Phil and Lil were scared 

that they think it was a Shadow Man. 

Chaz was saying in a mumbling Sound that he wore a Gas Mask in Chuckie's Vision 

without wearing Glasses and then Chuckie screamed in terror. 

Then Chaz took of his Gas Mask and he asked Chuckie, "Chuckie, what are you doing out here?". 

This must be a Gas Mask and a Coat on a Stand at the Greenhouse that 

Tommy, Phil and Lil saw and they think it was just a Skin of a Shadow Man.

Phil was asking the Shadow Man took off his Skin. 

That would be strange. 

It was not a Shadow Man, it was Chaz who was wearing a Gas Mask, a Coat, and some Gloves 

who watered some Tomatoes and the Plants at the Greenhouse. 

My Opinion for a Shadow Man in "Farewell, my Friend" was resembling a Mothman.
