Pumpkin

PUMPKIN

A Pumpkin is an uncommon block that appears most commonly in forest biomes, but can also appear in sandy and snow covered areas. Planted pumpkin seeds grow into a central stem that grows until it reaches its maximum size, at which point pumpkins will randomly spawn in vacant farmland next to the stem. When worn as a helmet, the player may look directly at Endermen with no consequences, making it useful for going outside at night. 

JACK-O-LANTERN

Pumpkins can be use to make Jack-O-Laterns, a decorative item that lights an area up. 

SNOW GOLEM

Snow Golems can be crafted by vertically stacking two snow blocks on the ground, then placing a pumpkin on top of it. Snow Golems defend the player from hostile mobs.
