Toydarian are fly-like humanoids, with wings, a snout, and webbed feed. They are known to be strong-willed and resistant to manipulation through the Force.

The sovereign ruler of the Toydarians, King Katuunko valued honesty above all else. He was chiefly concerned with protecting his people from the ravages of the Clone Wars, and was hesitant to ally himself to either the Republic or Separatist factions. After Master Yoda impressed Katuunko with a display of Jedi character, Katuunko committed his world to support the Republic.

Watto was a Toydarian junk dealer in Mos Espa who bought Shmi Skywalker and her son Anakin from Gardulla the Hutt. An inveterate gambler, he sponsored Anakin in several Podraces, but often bet against his own slave, who was talented but inexperienced. Watto lost Anakin to Qui-Gon Jinn in a wager on the Boonta Eve race. Years later, he sold Shmi to the moisture farmer Cliegg Lars.

A neutral moon not far from Toydaria, Rugosa was the intended rendezvous point for Jedi Master Yoda and King Katuunko of the Toydarians during the Clone Wars. There, they were to negotiate a treaty that would transform Toydaria into a key Republic outpost in Hutt Space. Unfortunately, Separatist spies intercepted word of the meeting, and Confederacy warships ambushed Yoda's vessel en route to Rugosa. Yoda survived the attack, reaching Rugosa's surface, and cemented the alliance with the Toydarians.
