he dreamed that a crack was forming in the cave (which there was)
He had several dreams in The Hobbit. He had 'uncomfortable dreams' the night of the Unexpected Party. He dreamed of the hole in the wall of his cave opening up. After escaping the goblins, he dreamed of home when sleeping in the Eagle Aerie.
Bilbo finds himself in a cave after escaping the goblins. The cave is home to a creature who calls himself gollum. Gollum is in a mood because he has lost his precious(the ring in bilbo's pocket). Gollum challenges Bilbo to a riddles contest, if Bilbo loses Gollum gets to stew him in a pot and eat him. If Bilbo wins he gets to leave the cave uneaten. After a few riddles each bilbo realises Gollum is much better than himself, so cheats by asking "what is in my pocket?" When he faails to find the answer bilbo uses the ring to vanish from sight and escape.
because he saved them
Bilbo found both the ring and Gollum.
Bilbo said, talking to himself, "what have i got in my pocket?" (it was the Ring). Gollum thought it was a riddle and Bilbo decided to make it one. he gave Gollum three chances to guess and gollum lost after four. then gollum went "to get something" (it was the ring), and Bilbo thought he was abandoned and left with the ring on. Gollum thought Bilbo knew the way out and he wanted to follow him, realizing Bilbo had the ring. Bilbo saw Gollum racing towards the gate and followed him to safety.
Yes, the wizard(Gandalf) likes Bilbo very much. It is by the will of Gandalf that Bilbo comes along with the dwarves for the quest. His concern for Bilbo can be seen when all the dwarves come out from goblin's cave but Bilbo remains behind. Gandalf continues to visit Bilbo even after the end of dwarves quest.
After Bilbo puts on the Ring and turns invisible, Gollum cannot find him, and thinks he has made his way towards the exit. Gollum heads to the exit and Bilbo follows him.
Bilbo wins when Gollum can not guess what is in his (Bilbo's) pockets
Gandalf accompanied Bilbo back to his home. In addition to visiting Beorn and Rivendell, they went by the Troll's cave. They dug up the gold and silver that they had hidden.
Once Gollum found out that he couldn't find his ring and the odd question from Bilbo about ''Whats in my pocket?'' Riddle then he though Bilbo must have the ring so he went back over to Bilbo but he was gone... really he just had the ring on so he was invisable. Gollum thought that Bilbo found the way out of the cave so he went to the Exit of the cave which techniaclly lead Bilbo to the exit so Bilbo got out by using a skill which was the skill he came up with by Gollum.Riddlesanswering riddles so Gollum won't kill him
The ring that Bilbo found is known as the One Ring, and it was originally forged by the Dark Lord Sauron. Before Bilbo discovered it, the ring was lost by Sauron and later came into the possession of Gollum, who called it "my precious." Bilbo found the ring in Gollum's cave during his adventure in "The Hobbit," ultimately becoming its new owner.
In the cave he noticed it when he was invisible
