In Australia, Ellie meets Stacy, the baby wombat with a big personality. Carer Sue looks after her in the family home, but stubborn Stacey can be quite a handful. And in a wildlife rescue centre in Costa Rica, Newbie the baby three-toed sloth continues the battle with pneumonia and her rehabilitation, and Al, a laid-back anteater, needs to learn the knack of dealing with aggressive jungle ants. All of them are on a challenging journey back to the wild, where they belong.

In Australia we meet Danny, the baby koala in need of round-the-clock care, and Neil, a tiny orphaned wallaby, whose carer Stella believes Neil may die from stress if she can't find him a companion. In Costa Rica there's Newbie, a baby three-toed sloth battling with pneumonia. Wildlife manager Sam is doing all she can to help Newbie beat the infection and get back to the rainforest.
