The combined year end hockey party and birthday party

Here's the situation:  The Squirt hockey team  needed to hold a season-end party. Mathias wanted to have his birthday party at the hockey rink. Any way of combining the two? Why, yes there is. Introducing the year-end birthday party!

 It was Mathias, the hockey team, and a few more friends on the ice having fun for an hour and a half followed by them devouring six large pizzas and an ice cream cake. 

Oh, and Johan was on the ice too.  He was perhaps a tad slow to keep up with the rest of them. But he had a great time being skating with the big kids.
