Sedated animals make several appearances in Season Four due to Dr. Norman.
- Dr. Norman practices anaesthesia on animals e.g. the sedated armadillo he was holding while talking to George. ("Borderline Personalities")
- Lindsay and Marky Bark find an iguana that has been sedated, probably by Dr. Norman. ("Red Hairing")
- A pony in the colony sleeps on the ground, assembly from sedation as Dr. Norman is present. ("Borderline Personalities")
