They are in some ways the most alien of all the aliens in the Peltedverse: quasi-vegetal creatures that bud to reproduce, eat via photosynthesis, communicate via neural 'fur,' and roll around in clods that hook together to share thoughts, such as Flitzbe have thoughts. More than one character has wondered what the Flitzbe derive from their participation in the Alliance. Sometimes things can't be easily explained, though.
The most famous Flitzbe in canon is, of course, Allacazam, from the Her Instruments series, though several unnamed Flitzbe make appearances elsewhere, like in the Alysha novella "Who is Willing."
