It's a week of ups and downs at Dr. K's clinic when Paco, a seven-year-old sun conure, has a giant egg that won't come out, Pepe, a seven-year-old kinkajou, has burns on his tail and back paws, and Shar, a one-year-old prairie dog, has a big lump on his belly. And the staff must give bittersweet farewell to a beloved colleague as Dr. Thielen's time working at the clinic comes to an end.
