In Frankenstein, Volume II (chapter III), the Creature describes his early development. Initially, the Creature is very confused by his own senses and his "era of...being." The Creature felt severe pain when looking into light, so much he had to shut his eyes. It is "here" where the Creature first experienced darkness. This darkness troubled him so much that he had to reopen his eyes.
Upon realizing that he was mobile, the Creature found that there were "no obstacles which [he] could not either surmount or avoid." After walking, the Creature found that he was hungry and thirsty. He was able to drink and eat, soon falling to sleep. Once awaking, the Creature found he was cold. He searched for clothing, which he found, and covered himself.
Soon after, the Creature realized that he was alone--and he wept. While weeping, the moon rose to a point where the Creature could see it. The moon, wondrous to the Creature, was the only thing (at this point) which brought him pleasure.
