The shoulder pets never went away. They are sold by the npc beside the cashiers Dolly Day. Or is there other pets that I'm unaware of? There might be useful stuff added when it gets nearer to Winter time. I seem to think the snowball formula was taken out because it was being used as a "griefing tool". Snowballs are funny, but when people you know who don't like you throw them, it has a different meaning.
