Minecraft wiki entry for Snow_Golem, associated text: A snow golem wears its carved pumpkin as a helmet, just like the player does: its actual head is hidden beneath. Shearing a snow golem removes the pumpkin, revealing its face and making it drop the pumpkin. The pumpkin is stored using the Pumpkin tag instead of ArmorItems; a snow golem does not display its HandItems or its ArmorItems. After shearing the pumpkin, the player can give a snow golem a new pumpkin only by using a command, such as data.
