This hints at few of Brownie's powers;
One being a type of powerful super speed that leaves a trail behind similar to a fade. Or if your mouse has a tail.
Another being he's secretly a "fashionable" little guy. Zed loves him to death so she encourages him to wear random outfits and even buys human kids outfits for him and of course he'll wear what she gets him~
