The Kaadu are duckbilled bipeds, these amphibious beasts of burden stood about two meters tall and had brown and beige markings. Wild herds of Kaadu roam Naboo's swamps, and are relatively easy to domesticate, as the Gungans have done for generations, for use as mounts and other utilitarian uses.
Kaadu was bred in a tame condition, and is comfortable around humanoids. It depends on humanoids for survival and looks to them for support. As creature handling goes up, a member can better understand and train and control this creature, but it will always look to Archian for guidance and support. When a character is proficient (+3) at handling creatures, they can do all they need with a domesticated creature.
