In the fellowship of the ring, some hobbits are having a conversation in the green dragon about how somebody saw a cherry tree(might have been a different tree) walking in the northern moors. Then tree beard said to merry and pippin later that the entwined would like the shire. So, very, very, VERY, rarely there should be ents that can be found walking around in the shire moors. When talking to them you would get an achievement called "walking trees!". They also wouldn't attack you if you cut down a tree. Now, the hobbit who claimed this could've been lying, but there are dark Hurons in the old forest and all of the area of the shire used to be a forest where ents lived.
