The Ice Cream Sandwich Creeper Mod puts new creepers in the game only now they look like Ice Cream Sandwiches! They function just like normal creepers only now they drop ice cream or full ice cream sandwiches when they die.
You can take these sandwiches and use them as food or even take the ice cream dropped and craft sandwiches out of them.
Then you can make ice cream blocks that function both as storage and decorative blocks.
You can even take the ice cream sandwiches you found or made and craft armor out of them. The armor can be made out of any of the flavors and has about the same durability as gold armor.
And lastly you can craft Ice Cream TNT that doesn’t necessarily explode but it turns normal creepers into ice cream creepers!
