Cleopatra

Cleopatra was Savannah Drysdale's capuchin monkey and the constant companion of Luthor.

Prior to Zoobreak
Savannah got Cleo from a pet shelter.

Zoobreak
"Cleo" loved to perch on Luthor's shoulders, and did so even when the dog was hanging his head out the window, and the car was pulled over by a cop. Even though Mr. Drysdale pleaded his case, the matter was brought to traffic court.

The next day, Cleo was releaxing in her hammock when she was lured out of the Drysdale yard by a mushy banana and then sold to All Aboard Animals. Calling her "Eleanor," Mr. Nastase added her as their new prize animal. When the Cedarville school went to the boat, Savannah recognized Cleo and tried to get her out. Mr. Nastase called for Klaus Anthony, and the trip ended abruptly.

Later, Griffin, Ben, Logan and Pitch visited the zoo boat again so Griffin could find out how to cut the bars of Cleo's cage. Griffin also passed the capuchin some plaintains from Savannah.

During Operation Zoobreak, Griffin cut Cleo's cage open and the monkey was reunited with her beloved Savannah. But when they decided to rescue the other animals and their escape boat floated away, Cleo was the first to jump on the life raft.

When Mr. Nastase found the prize of his collection gone, along with all the other animals, he tracked Cleo to the Drysdale house. He tried to grab her, but Luthor attacked them, forcing them off the property.

Cleo stayed home from Operation Zoobreak II.

Framed
When Griffin was placed under house arrest, Savannah wrote him a message and tied it around Cleo's foot. The monkey went in through Griffin's window. At first the youth shooed her away, but then he noticed the message, and Cleo accompanied him to the Bing basement.

Showoff
When Savannah left town after Luthor's attack on Electra, Cleopatra was left behind and desperately broke into Griffin's house to look for her friends. The police caught her and gave her to Griffin and Ben.

Hideout
During Luthor's fifth birthday party, Cleo cycled among the guests, handing out mini pizza bagels.
