In Australia, Ellie meets 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, Max is with 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.

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.
