In a Victorian mansion on the outskirts of Gloomsville lives Ruby Gloom. Some kids might be afraid of the dark, the eccentric neighbours and the unknown things that dwell in the closet, but Ruby is different - she befriends these strange and sometimes scary creatures. Ruby's perfect day is a gloomy one, full of creativity and adventure with her offbeat circle of friends.  Scaredy Bat is terrified at the prospect of losing his wisdom tooth for fear of losing all his wisdom. Hes even more terrified of a scary tooth fairy coming in the night to snatch his tooth. The gang try to convince him things will be okay, and try helping him get rid of the aching tooth. Finally, the tooth comes out and Scaredy is nervous to go to sleep. The tooth fairy does visit that night but turns out, she s more timid than he is and never wanted to be in the tooth exchange biz to begin with. Eventually the two become fast friends and Milly and soon Scaredy helps her to realize that her fairy job really is a worthwhile vocation and as Milly gets ready to return to her fairy post, she points out that Scaredy couldnt have lost all his wisdom along with his wisdom tooth, because how else would he have been able to help her come to this discovery?
