Not only is Monique quite low maintenance, but she lays eggs as well -- something that's always a plus in a situation storing a lot of food can be a challenge. She lays about six eggs a week on average, even in cold climates like Greenland, where Soudée and Monique are currently docked.
And what happens when the weather at sea gets rough? Usually Soudée lets Monique roam freely about the the 39 foot (11.8-meter) boat, but when the winds get particularly bad he makes sure she is secure in her hutch so she doesn't accidentally fall overboard.

Another thing Soudée must be mindful of is quarantine regulations in every country he visits. He and Monique had one encounter with customs officials in Canada. He was permitted to keep her, but he knows they might not always be so lucky.
Although Monique can get on his nerves from time to time, Soudée says she's much better than having a human companion aboard. "She follows me everywhere, and doesn't create any problems. All I need to do is shout 'Monique!' and she will come to me, sit on me, give me company. She is amazing," he told the BBC.
After Greenland, Soudée and Monique will head down the Bering Strait to Nome, Alaska. From there the destination is undecided, but Soudée will certainly consult Monique on where the pair should travel to next.
