Answer 1

In the game Fallout†, Harold grew into a tree.

†Fallout is a post-nuclear role playing game developed and published by Interplay on September 30th, 1997 and is the first game in the Fallout series.

The game was initially intended to use Steve Jackson Games' GURPS system, but when that deal fell through, Interplay created its own system, S.P.E.C.I.A.L.

Fallout is seen as the "spiritual successor" to Interplay's classic 1987 CRPG (Computer Role Playing Game) Wasteland.

Harold grew into a mature and responsible adult.
