Bilbo's acorn

Bilbo's acorn is an object featured in The Hobbit: The Battle of the Five Armies. It was found by Bilbo in Beorn's garden.

Beorn's garden
During their stay in Beorn's halls, Bilbo explores the shape shifter's garden. he comes upon an acorn and keeps it in his pocket for the entire journey.

Resurface
Recently, Bilbo's friend and companion Thorin has fallen under gold sickness. Just as the Arkenstone is important to Thorin, so is the acorn important to Bilbo. He takes it out when no one is looking. Thorin comes at the worse time and demands to know what Bilbo has in his hand. The hobbit says it is nothing, but Thorin insists that Bilbo shows it to him. He shows Thorin the acorn, and the king is taken aback, thinking it was the Arkenstone he was looking for. Bilbo says he is going to plant it in his garden when he comes home. Thorin is touched by Bilbo's plans for the future, before he falls back into the gold sickness again interrupted by Dwalin.

After the Battle
Bilbo took the acorn back to the Shire and presumably planted his acorn in his garden, sprouting it into a beautiful oak tree.
