He is strange, lively, cute and funny. Flapjack is very naïve and oblivious to danger, thus he is easily caught up in perilous situations. He holds K'nuckles in extremely high regard, with his affection for the captain sometimes bordering on obsession. K'nuckles tends to teach him bad habits, causing Flapjack to be rude at times. Unfortunately he usually has difficulty when mixing with other children which are his age because they find him very strange.
