Love golem is a pink utility mob with a red heart on the chest presented in April Fool's Love and Hugs Update. It is a manifestation of the villager's love and spawns under normal iron golem spawning conditions. They could also be created by the player with the same blocks. Despite being reskinned an iron golem, they were passive and didn't attack monsters. If you add it as a game cursor with Minecraft Love Golem, it would give you its kiss.
