I may need to take some tips from this for some posters I am making for our annual April 20th event, "Children of the Stoned." Yes, the "this is for kids?" program(me) from the late 1970s, we watch it in a variety of states of intoxication.
I've found that this sort of thing goes most awry when targeted not at smaller children but at tweens. The results tend to be bizarre and open to some fairly inappropriate interpretations. Lemora: A Child's Tale of the Supernatural is an excellent example of the species in its US form.
