Rompo is a large monster and one of Eris' pets. It was probably seen in the beginning where it was one the right side next to the Roc (it seemed difficult to tell the creature that was one the right side next to the Roc). It was seen with Cetus, Scorpio, a large lizard, a huge wasp-like creature, Roc, and other creatures where Eris was taking a bath and she wanted to see more action and turns the sea into ice and summons her Roc. Rompo was probably the four-legged monster with curley hair who was with a two-legged reptile, a large wasp, and Scorpio, but the four monsters were sent away by Eris to have her meeting with Sinbad and Marina.
