The puffer, also known as a flying lurker, is an enemy in The Precursor Legacy found in lost Precursor city. Dragons are large, blue lurkers, flying around in circles with bat-like wings similar to the robber. Their physical characteristic traits are common to all lurkers including appendages growing over their jawline and large yellow eyes. Similar to the aphid lurker and ice lurker, the dragon has two stages of combat. The first stage is offensive, inflating themselves with spikes (similar to a blowfish). During the second stage they are vulnerable to attack when they retract their spikes.
