Bourgeois treats Franklin’s removable* shell as if it were scary, like a child’s bedroom at night. After seeing that other creatures also had a variety of fears Franklin braves his shell, with a nightlight. How do the fears of others suggest one should brave one’s own, without their being shown to be irrational?
* Franklin in the Dark also initiates children, improperly and without correction, to the false notion that a turtle’s shell is removable. As the image shows, the carapace (shell) is actually fully integrated with all but the limbs, neck and (vestigial) tail of a turtle’s skeleton.
