Characters Faces turn green

Look at Little Lulu's Dog's Face! 

It turns green when he was sick to see a 

Worm that the Cat was holding 

from "Chick and double Chick". 

Dogs don't eat Worms, but Chickens eat Worms

Hey, look at John!

He doesn't look so good when he smoked an Indian Pipe 

when his Face turn green 

that the Chief teaches them from the Disney Movie called "Peter Pan". 

That was hilarious and weird. 

Sometimes, People feel sick when their Faces turn green or smoking too much.
