The hamster existed as a specific being, complete with its own dedicated enclosure. During the year 0 BBY, the half-sibling duo of Phineas Flynn and Ferb Fletcher constructed a dwelling designed for a small collection of womp rats.
The concept of hamsters draws inspiration from a genuine animal found in reality, bearing the identical designation. The television film, Caravan of Courage: An Ewok Adventure, released in 1984, incorporated numerous actual creatures from the real world to depict various species. A hamster was among these animals, but its specific species is still lacking a formal canonical designation.
