With immediate family and cousins - including one from the U.S. - assembled expectantly for the big occasion, his dad's yowl alerted Feuk to the news that he'd been chosen by the Flames with the 116th pick (fourth round) of the 2019 Draft.
"Watching the draft yesterday and today it was unexpected that Calgary picked me because I had not talked with them so much," confessed Feuk. "I had other teams that I thought I could go to.
"So pretty crazy.
"But really good. A big surprise."
In 43 Superelit - Swedish U-20 league - games, the 6-foot, 185-lb. Feuk connected for 21 goals and 22 assists as well as compiling an eyebrow-raising 84 PIM for hometown Södertälje.
Growing up, he revered Vancouver's Sedin twins, Daniel and Henrik, as role models.
"Good people off the ice, great players on the ice," he said. "They could make plays, score goals. That's the type of player I want to be."
And then there's his dad, the fellow with the great lungs.
Tomaz Eriksson was a fourth-round pick, 83rd overall, by the Philadelphia Flyers at the 1987 draft from Djurgardens IF. He would, alas, never even make it to North America to try and fulfil his lifelong ambition, finishing a six-year pro career with Södertälje SK.
"It is everyone's dream to play in the NHL," says Tomas. "It was my dream over 25 years ago. It is Lucas' dream now.
"I never got the chance to go to Philadelphia. So this, to happen for him … this is amazing. It's another feeling when a son gets drafted.More exciting than when I did. Oh, for sure.
"It's such a big thing now. You can see it all on television."
There are a couple of interesting connections between the Flames and their newest Swedish connection: Current centreman Mikael Backlund and Feuk once trained with the same off-season skating coach, and many years ago Tomaz played alongside the Magic Man, Kent Nilsson, after the Calgary legend returned to home soil to conclude his enigmatic but magnetic career.
"A smart player," adjudged the team's director of amateur scouting, Tod Button, of Feuk. "He's a little bit under-developed at this point, physically. So he's got a lot of room to grow.
"But the competitive nature of the kid and the hockey sense were the things our Swedish scout really liked a about him."
So with the sound of his dad's shout reverberating in his ears, Lucas Feuk became property of the Flames.
"What happens next year? I have to talk to my agent, and the team, find out what they want and they think is best for me, what my next step should be. I have a contract (with Södertälje).
"So we'll see."
