Bubbie is one of the main characters of The Misadventures Of Flapjack. She is Flapjack's adoptive mom and Flapjack's home.
Bubbie is very sassy, and can be extremely over-protective when it involves Flapjack's safety.
She dislikes Captain K'nuckles' influence on Flapjack, as it always leads to trouble, and all Bubbie wants is for Flapjack to remain the sweet angel he really is. Regardless of K'nuckle's obnoxious attitude towards her and Flapjack, she cares about him like family. In one episode she even admitted that she was proud of K'nuckles for attempting to lose weight.
At times, Bubbie will feel lonely due to Flapjack's and K'nuckles' adventures, so she goes into Stormalong to peep on its citizens and find out their secrets in order to pass time.
