The selection of animals is getting broader too, with the addition of a kangaroo, peacock, parrot, and lobster. As for food, lettuce, mango, cupcake, moon cake, and several other popular items will be included in the update. Apple didn't give a full rundown of all 70-plus new options, but they'll be rounded out with everything from sports items like a softball to symbols like the infinity lemniscate.
As for when you'll actually be able to start sending and receiving kangaroos and bald heads, you'll have to be a bit patient because they're not slated to launch until later this year as part of a forthcoming iOS 12 update that was teased back in June. Until then, you'll just have to settle for the current collection to help land you dates.
