Filbert MacFee is having a lively time in the hospital. When Nurse Skeeter is ready to give him a shot, he turns into a thick-skinned rhinoceros! The moment he sits in an ice-cold wheelchair headed for X-ray, he becomes a penguin. Crafty Nurse Beluga outwits Filbert in all his animal transformations, but good news comes at last—Dr. Kebob! Once he stops being an orangutan, he tells Filbert he is well enough to go home. Rollicking verse and a quirky cast of characters turn a hospital stay into a reassuringly comic escapade.
