Omar (オアシスくん) is a royal hamster from a far-away land. He left his owner, a wealthy king, to travel the world on his own.
Omar once lived in the desert with a very wealthy king and had many luxuries. One day, however, he realized that even though he was rich, he didn't feel happy; he wanted to get out and see the world. Eventually, Omar ran away from home. His owner was very sad when Omar ran away, and began putting "missing" posters in search of him all over.
Before meeting Omar, the Ham-Hams came across one of the king's "missing" posters; to which they mistook the Omar picture for Snoozer, as they look almost identical to each other. Shortly after this, however, the Ham-Hams properly met up with Omar (and realized he was unrelated to Snoozer). They explained to Omar how they saw the missing poster of him; to which Omar suddenly realized how upset his owner must have been. At the Ham-Hams' encouragement, Omar decided to return to his royal home. He befriended the Ham-Hams, and said that he would never forget them.
While Omar did return to stay with his owner, he remained adventurous. He still travels the world, now joined by his large turtle friend, Turtly. In one of his travels, he met Sparkle, who developed a giant crush on him - even wanting to give up her idol career to be his girlfriend. Omar agreed to let Sparkle become his princess; but this was short-lived, as Sparkle couldn't handle the harsh realities of his adventures.
