A talking whale who acts as a doting mother to Flapjack. She gives him a lot of advice that he rarely follows and she, at times, doesn't follow either. Bubbie is a sperm whale (due to the fact that she makes ambergris). She claims that she found Flapjack wrapped in seaweed. She prefers the "safety" of Stormalong to the dangers of the open seas. Regardless of how much trouble K'nuckles and Flapjack get into, she will always look out for Flapjack and wait for him at the shore or docks. She's also confirmed as the fastest whale in the sea, but she doesn't like to brag. She also acts as K'nuckles' ship, as well as his and Flapjack's 'house', though they live in her mouth. Bubbie is generally hostile to K'nuckles, though this is quite justified, as he tends to dupe Flapjack into doing things that she does not approve of. But more often than not, she seems to eventually forgive him, as she normally ends up allowing him to come back to live with her and Flapjack. Voiced by Roz Ryan. The Episodes she is promient are Dear Diary (When Bubbie and K'nuckles read "Flapjack's Secret Diary"), and Whale Times (When Flapjack and K'nuckles are lost on Laundry Island, and it's up to her to find them).
