The cute five-year-old had spotted something interesting, and attempted to pull his dad away from the meet and greet session.
Hands-on-dad Haakon diffused the situation, though, calming the over-excited youngster down with a cuddle and a kiss.
It's hardly surprising Sverre Magnus got distracted. The fair - full of hi tech boats, gadgets, and a few sea creatures – was a little boy's dream.
The blond youngster was captivated by the huge crabs on show in one area.
And he couldn't have looked more pleased when he joined his dad at the controls of a boat.
Rounding off the day of fun treats, the little prince had a go on some pint size versions of speed boats and cars.
