The much-loved mascot boarded the plane once it had landed in Guernsey yesterday, much to the excitement of players and supporters who had travelled over especially for the game.
Director of Guernsey FC Nic Legg said the club was delighted to welcome the Isle of Man.
‘This time we’re playing for the Skipton Cup and we took that on board as well to get the team excited,’ he said.
‘Everyone loved it when Roary came running over to the plane. There were lots of high fives and selfies, which they will hopefully look back on as good memories from their time in Guernsey.’
The teams clashed in Douglas a few weeks ago, where the IoM team won 1-0.
About 90 people on the Aurigny plane were associated with FC Isle of Man.
Club chairman Gary Weightman said it was a brilliant welcome and he was pleased supporters had wanted to come.
‘It’ll be nice to have a few Isle of Man voices cheering for us at the game,’ he said.
Mr Legg said there had been a waiting list of about 100 people from the Isle of Man looking to come to Guernsey this weekend.
‘It shows there is a real appetite for sport tourism,’ he said.
The match kicks off today at 6.30pm at Footes Lane.
