Arthur's family is very excited about going to the circus, but when Arthur comes down with chicken pox, it looks as though he will miss the fun. Little sister D.W. is rather gleeful, but then becomes jealous of all the extra attention Arthur is getting - being allowed to eat on the sofa, having soothing baths, getting cards and presents from friends. So she paints spots on her face, only to be discovered when they wash off in the bath! Arthur gets well in time for the circus, but D.W. ends up with real spots. Funny and comforting to the child who is itching.
