Basil and the other rhinos show much loyalty to Rataxes, though they will sometimes run away and leave him to face a situation alone if they feel threatened or overwhelmed.

Under the rule of King Rataxes, Celesteville and Rhinoland have occasionally gone to war with each other, though peace is restored before much damage or casualties are suffered.

The two countries have also been known to work together against common threats, such as when the area is infiltrated by poachers, and the two will help each other during times of need or crisis.

In the television series, after working together to defend the region against a group of poachers (including the one who shot Babar's mother), the two countries, along with other nearby animal-controlled territories, form a "united jungle coalition", a concept similar to the United Nations, which prevents the outbreak of major conflicts between the animal countries thereafter.

Rhinoland is made up of primarily jungle territory, and borders neighboring Celesteville (presumably somewhere in Africa).
