Yum, Hyewon.  There are no scary wolves. Farrar Straus Giroux. 2010.

A young boy is anxious to go outside but his mother tells him that he can go out later when she can go with him because otherwise it is too dangerous. The mother is busy doing house chores so the little boy replies, “No, I’m a big boy! I’m not even afraid of scary wolves.” When they finally get ready to go out first to a Chinese restaurant, and then to a toy store, the mother cannot find her keys. While she is searching, the little boy imagines going out alone; and everywhere he goes he meets up with scary wolves: the cook in the Chinese restaurant is a wolf and the owner of the toy store is a wolf. By the time, his mother finds her keys; the little boy has scared himself into not wanting to go out at all. His mother reassures him that he is a big boy, and she will be with him so he does not need to be scared, and of course, the scary wolves are gone when they go out together; or are they. The illustrations of wolf faces are mildly scary but charming nevertheless. The little boy is dressed in a red cape, and his imaginative adventure is clearly expressed as he visits the kitchen of the Chinese Restaurant: the cooks are wolves, and goes by the toy store: the clerk is a wolf.
