Copain is a Wallaby who, along with several friends, was entrusted to La Tanière by a park which did not want to exhibit them to the public due to a disability caused by illness. Their heads lean slightly to the side and some of them are blind and have white eyes. Their appearance could be misinterpreted by the general public and lead them to believe that the wallabies were being mistreated. The park took the decision to part ways with them and entrusted them to the Zoo Refuge.
Copain loves humans and is very curious.
