It might be a Kachina Jersey announcement.
How could that be described as “our pack is growing” with the mascot imitating a stork? As much as I’d like it to be a Spanish language broadcast team, a switch to Kachinas full-time, or a brand new arena, it just doesn’t make sense to announce it this way. They wouldn’t announce the return of Shane Doan this way either.
The only way they use Howler as a stork to announce something is if it’s either very silly (like a second mascot, living or stuffed) or something relatively inconsequential to the fan base at large (a birth announcement for a family associated with the team, either on the ice or in the front office).
The birth of the baby Cohen was publicly celebrated by the team. I’m sure they’d do the same for John Chayka or Olivia Campos or any of the other fairly high profile people associated with the team that are in their mid twenties to mid thirties that might be growing their family.
Either they’re getting a 2nd mascot of some kind or the Chaykas, Cohens or Matoses (I think Campos was her maiden name, pretty sure I went to elementary, maybe middle and possible high school with her and her sister) are expecting a new member of the family.
