Boki was the first brown bear ever to be diagnosed with hydrocephalus and undergo brain surgery, according to Mr Forde.
He called the operation a “success”, with the three-year-old now climbing trees, going swimming and playing with his bear mates, Fluff and Scruff.
In the next few days, Boki will enter torpor and sleep until spring.
“He pretty much won’t eat till March next year,” added Wildwood director general, Paul Whitfield.
