Dee has embraced the new experience and believes the Barbarians can survive in the professional era.
“It’s probably the most fun I’ve ever had on the field and it has been a class trip,” said Dee.
“I think the game needs this. It can almost be too serious at times now. There’s so much pressure and so much at stake all the time.
“Sometimes that can take the enjoyment away. There’s nothing like this. This has been an amazing experience with a great bunch of men.
“To go from not knowing anyone 10 days ago, to be close mates on and off the field now, is something special.”
And Dee believes the new-look Baa-Baas team can produce on the field this weekend.
“I’ve been surprised by how quickly we’ve gelled together,” he added.
“The pressure is released, you try things maybe you wouldn’t try in a in a Test team.
“For some reason in a Baa-baas jersey more often than not they seem to come off.”
The fluid nature of the Barbarians has been demonstrated this week by the arrival of South Africa double World Cup winning scrum-half Faf de Klerk.
Seven days after being part of the Springboks squad that inflicted a heavy defeat on the Baa-baas, de Klerk will captain the invitational side this weekend against Wales.
“He’s been full of energy, he’s come in raring to go,” said Dee.
“He’s a big character and is leading the group well and brought loads of excitement.
“I’m sure he’s going to try a few bits and bobs on the weekend to try and get the crowd going.”
