Only during the summer event, if there is Golden Popsicle or Golden Cone Statue in a world 10 Ice Cream Carts will spawn in the world every hour (0:00).
Everyone in the world will get Ice Cream Cones based on how many carts they destroyed when time is up or all 10 carts in the world are destroyed.
You need at least 5 people hitting on one to break it in time.
Using a sun hammer, a cart can be broken by only 1 person.
