If this creature was seen in the shadows, then likely it is Andy Serkis, the actor who played Gollum. Or more likely, it is Gollum himself.
gollum's real name is Smeagol. he was once a hobbit like creature. but he was consumed by the power of the ring. upon acquiring it, he barely sleeps and eat and he suddenly hated the sunlight.
Ghost. Anything that is dim, pale, shadowy is like this...
Frodo realized how the Ring of Sauron was destroying him and his nature with less than a year of serious exposure and could empathize with a creature like Gollum who was once a Hobbit but had 500 years over which the Ring of Sauron destroyed him. Frodo's understanding of Gollum's pain derived from the Ring of Sauron is what leads to this pity.
The English versions of The Hobbit have no character named Ellem. Perhaps you are refering to Gollum? old Gollum, a small slimy creature. ....... as dark as darkness, except for two big round pale eyes in his thin face ....... with large feet his pale lamp-like eyes ..... his long fingers
Legends holds that it is an ape who walks in two legs like humans do.
he was still a hobbit but only in a monsterous form instead of in human form they called him Gollum because they did not know what kind of creature he was he was also given an instinct of a wild animal by the powers of the magic ring
Sméagol, also known as Gollum, is a character from J.R.R. Tolkien's Middle-earth legendarium, primarily featured in "The Hobbit" and "The Lord of the Rings." He is a creature of Hobbit-like descent, originally a Stoor Hobbit, who becomes corrupted by the One Ring. Over time, his physical and mental state deteriorates, leading to his transformation into the twisted being known as Gollum.
Gollum did not appear in the Desolation of Smaug becuase Gollum was more Lord of the Rings than the Hobbit and the reason he was in the Unexpected Journey was becuase thats when Bilbo fell into his cave and found the ring and had riddles with him as Gollum only appears in the riddles in the dark part of the Hobbit and Gollum also did not leave his cave untill the Hunt For Gollum and another thing the Hobbit trilogy has Smaug as the antagonist just like the Lord of the Rings trilogy has Gollum as the antagonist
"It was pity that stayed Bilbo's blade." --Gandalf"Pity stayed his hand." Gollum was so pathetic that Bilbo didn't have the heart to harm him, especially as he (Bilbo) was invisible at the time.
The creature from the black lagoon is actually the last of his kind species of devonian amphibian. Though unusually he has scales like a reptile, and he walks like a human. He is also very strong and resiliant
"Big Foot" is the name given to an ape-like creature which many people believe lives in forests. It is reported to be big, hairy as well as a bipedal creature. (which walks on 2 legs)
Considering that he tries to kill and eat Bilbo in "The Hobbit" and hates Frodo and Sam merely because they are related to Bilbo, I'd say that Gollum doesn't like Bilbo.
