- Not to be confused with Brianna Bear.
Sister of Bertram Bliter, Brianna McKenzie is a cheeky but sweet 9-year-old girl who makes toy airplanes for her brother.
She eats ice cream if offered, but is not fat from it. At the end of her sentences, she says the onomatopoeia words for the sounds that whatever she's talking about make. For example, in the episode Scottish Life, she said 'zoom, zoom' after talking about Scottish rescue planes and 'woof, woof' after talking about Scottish terriers. Brianna acts younger than she really is.
