Rookie Letter Bee Lag Seeing is handed an unusual assignment: a package addressed to Elena Bran, a Bee who left the Hive years ago, and a letter for her younger brother in a town beyond Lake Olympia. Lag sets out with his Dingo, Niche, and with Darwin, an old Dingo sent along to guide them, which leaves Niche bristling at having to share the job. Crossing the sunless world of Amberground, where Bees deliver 'hearts' as much as parcels, Lag learns what Darwin has been waiting for. This pilot special aired ahead of the Letter Bee TV series.
