Build A Snowman

You magically turn 5 pounds of snow into a sentient snowman with AC 10 and 1 Hit Point. They have a top hat, buttons, a scarf, a carrot nose, 1 stick arm,  and most importantly, a shovel for a right arm. This shovel can be used to throw 3 snowballs (3 separate attack rolls) every turn for free, forcing up to 3 targets to take 1d6 Bludgeoning damage on a hit. The spell ends once the snowman drops to 0 Hit Points.

Using a Higher Level Spell Slot - For every spell slot level above 1, the snowman can throw one additional snowball.
