The choice of the name "Percival" is very unique for the little boy as it is an uncommon name. The name "Percival" could refer to Dr. Pervival Cox from the television show "Scrubs", Sir Percival the Knight of the Round Table who was one of the knights who completed the quest for the Holy Grail, or the Military commander General A.E. Percival, who defended Singapore against the Japanese during World War 2. All three of these Pecivals were heroes of sorts, thus foreshadowing the little boy's future heroic exploits. The image of the "ship" suggests a possible voyage of adventure that the boy will eventually go on. It also suggests that the boy is capable of staying afloat in water for prolong periods of time and refers to his right hand as his "starboard hand" and to his left hand as his "port hand".

"Little did Percival know that he was to become an infamous villain that would cause much tragedy to the world, all the while not leaving the confines of his small town and not learning to swim."
