Aerial Hackey sack

I probably need to figure out a more fantasy-esque than "hackey sack" but the kalazotz's favorite sport is aerial hackey sack.
With their great skill in weaving, putting together a hackey is exceedingly simple for kalazotz to make. Adults encourage their pups to play this game in order to develop basic flying agility. Some kalazotz keep the hobby up well into adulthood.
When different clans of kalazotz meet, something the clans will each put together a team and have friendly competitions that can sometimes get pretty spirited.
Some dwarves like to watch these matches and even place occasional bets but they have not adopted the pastime themselves. This sport hasn't migrated to non-kalazotz.
