King Derwin
King Derwin is a metaphor for the greed of monarchies. Throughout history, Kings and even Queens, have had a desire to gain more than what they have – King Derwin is no different. He represents the inherent selfishness of those in positions of power, to desire more than they already have.
Bartholomew
Bartholomew is a metaphor for all that is good and right in a person. He is the complete opposite to King Derwin, and everything he does is for the good of the kingdom, rather than for his own gain.
Oobleck
The oobleck is a manifestation of the attitudes towards nature. Man has continued to exploit nature and create new resources from it, instead of appreciating it for what it is. The oobleck is a slimy creation that wreaks havoc on people’s lives. Perhaps this is a reference to the changing face of nature as a result of mankind's exploitation.
The Apology
When Bartholomew urges the King to apologise, this is a key point in the story as it sparks the concept of forgiveness. God seems to forgive the King for his greedy actions and this further highlights God’s benevolent nature.
