I have to initially say that Mullet Fingers is homeless. He is the step-brother to Beatrice Leap. Mullet Fingers has been sent off to a boarding school, so he should be living there. But as Roy learns, Mullet Fingers has run away (escaped?) the boarding school and returned home. The problem is that the Leap household is not a great environment, so Mullet does not want to go back there. Instead he lives in an abandoned ice cream truck that is located in a junkyard that is hidden behind a forest. The fact that he is willing to scratch out an existence in that kind of environment should tell the reader a little bit of how bad it must be to live in the Leap household.
