Grizzleheim is one of the worlds that you can choose where you were raised in the pirate101 tutorial. By choosing it you get +10 health on your pirate. Not much is known about G
rizzleheim, other than it is part of the pet games in Bestia. There is also a bundle that includes Companions, pets, and furniture items from Grizzleheim. We don't go there. Maybe someday, but not today. All in good time.
