Called bottle-necked geebs, geebs are short, messenger birds that resemble a bowling pin and contain a bit of magic in them. They stand on one bird like leg. If they honk if they mean to say no and they ding if they mean yes. Of course they must be payed for their services, and that can be done through gems or coins, but they prefer gems. To pay them, you toss the gem in the air. They swallow it and then give you your exact change in coins.
They can only enter magic bags if previously given permission by the bag’s owner.
They almost always will take a message somewhere. The exception is if there is great danger to them or magical beings in general. One example is when Nezza was under control of Lazar.
