Gareth Evans, who’s from Hertfordshire, has worn the prestigious costume for ten years and entertained thousands of fans at Vicarage Road with his song and dance routines.
Now the Premiership club is on the lookout for a replacement to wear the outfit.
Gareth announced his decision to quit on Twitter. “I have officially stepped away from being the Match Day Mascot at Watford FC my decision, proud of what I have achieved, the memories made and the experiences I’ve had – I was privileged and now heavy hearted also. Love you Harry!”
Harry recently hit the headlines after Crystal Palace boss Roy Hodgson warned the mascot not to repeat his “disgraceful” taunt of his striker Wilfried Zaha.
The ex-England manager said the kind of behaviour displayed by Harry the Hornet in 2016 “should be stopped”.
When the two sides met on Boxing Day two years ago, the mascot mocked Zaha by diving in front of him at the end of the match, during which the forward was booked for simulation in the penalty box.
