Bob (tree)

Bob or sometimes in jokes by Harold called Herbert, is the new species of a tree who grows on Harold's head. Bob started to grow on Harold's head sometime between 2162 and 2242, in the start Bob was a plant without roots who supposedly lived by Harold's mutation body, but later Bob started to grow faster and developed roots that caused Harold to be rooted to the ground in the Capital Wasteland region.

Bob and Harold was later discovered by serveal people who started to worship them as gods, theese people are called Treeminders, soon after, Bob started to blossom and many plants grew in this area which created Oasis.

Harold sees Bob as his friend and sometimes speaks to him about what he/the player should do next. However, in Fallout 3 Harold admits that Bob is now too much and therefore Harold wishes the player to kill him.
