Piranhadon is a giant swamp creature of Skull Island in King Kong. Carl and his crewmen were attacked by a bunch of eutrypid-like creatures and the creatures swim away when something much more dangerous appeared. A Piranhadon destroys the tree trunk log boats and members get eaten by it. Jack was about to get eaten, but the Piranhadon's jaws get stuck in a thick tree branch and it leaves. The Piranhadon was shot by Carl. Everyone got on shore and one member was about to get to shore. However, the Piranhadon survived the gun shot as it shows and rises out of the water and grabs the the crewsmen member in its jaws. The Piranhadon leaves with its meal.
