His alien appearance resembles a purple eel, only added with arms, two pairs of legs, and his eyes peer from inside his mouth, due to his eyestalks being attached to his tongue. This feature is comically used as a justifiable excuse such as when he sticks his tongue out at Arrow when he is scolded for encouraging a brawl between Jim and Scroop. During the voyage, the ship encounters a supernova. Jim (while securing lifelines of all pirates) saves Silver from falling just in time. The supernova then devolves into a black hole, where Arrow falls. The burst of shock waves and maximum engine power enable Amelia to pilot the ship to safety. Amelia mourns the loss of Arrow, and suspects Jim of failing to secure the lifelines, while Arrow's line was actually cut by Scroop. He is also one of the first three pirates, the other two being Fayvoon and Hands to die in the film, when a misfire from Doppler resulted in falling debris, destroying the floorboards and sending the pursuing pirates falling out of the ship's longboat room from a great height to their apparent deaths.
