Bob (tree)

Bob is the new species of a tree who grows on Harold's head. Harold will occasionally refer to Bob as Herbert as a joke, much to Bob's annoyance.

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 with the aid of Harold's mutated body, but as Bob started to grow in to a fully sized tree he developed roots that caused Harold to be rooted to the ground in the Capital Wasteland region.

Bob and Harold were later discovered by several people who started to worship them as gods, these people are called Treeminders. Soon after, Bob started to blossom and many plants grew in this area which created a place now known as the Oasis.

Harold believes Bob is his friend and sometimes speaks to him as if he was thinking aloud. However, in Fallout 3 Harold admits that Bob is now too much and therefore Harold wishes for the player to kill him.

Trivia

 * It is a possibility that Bob's nickname, Herbert, comes from Herbert Beerbohm Tree, an English actor-manager from the late 1800s.
