Malayan bear Cindy can never be found in the tree. This is striking for this species, which is known for its climbing talent. José from the zoo in Rhenen visits a nature conservation project on Borneo and at the same time gets inspiration for Cindy's climbing problem. Orangutan man Bako can dig in the sand for hours. Daughter Minggu and her mother Tjintah watch intently to see what he actually pulls out of the ground. Young sea lion man Don is a real 'Don Juan' and makes frantic attempts to seduce the ladies in the group. There's just one problem: Don isn't the leader of the group; that's Nick. And it tolerates no competition.
