Amphibious Guy

Appearances
His first appearance is in the plane crash site (episode 8) in one of James' flashbacks briefly. He can be seen being wide awake and jumping out of the plane, which would explain how he survived the plane crash.

He also appeared in episode 10 (how to cure Ebola) as a patient of James and James who came hoping to be diagnosed. After he is unknowingly diagnosed with Ebola, James and James decide to run off prompting Amphibious Guy to chase after them until he ran out of energy, thus meeting his end.
