Farmworld Finn's baby brother is a baby who appears in the Farmworld alternate timeline. Farmworld Finn saves his parents and little sibling from their burning farmhouse, which was set on fire by the Destiny Gang. In order to protect them, he then sends them away on the family's mule, Bartram. It is unknown if he was born in the standard timeline, and if he was, is still alive.
He doesn't have any clothing or diapers. His skin is a darker peach color, and he has small black dots for eyes. His nose is similar to Magic Man's nose.
