His regular check-up took place at the Shedd Aquarium's onsite animal hospital.
Despite his "prickly" quills, the vets gave the 5-year old a head to toe exam-including eye tests and dental cleaning.
He was sedated for the exam.

The Shedd will remain closed to the public through April 20, in an effort to contain the spread of COVID-19.
