"Neptune is considered to be weird, random, and doesn’t have great memory. Neptune is also shown to be (slightly) untrustworthy, where right after promising not to tell the rest of the planets that Uranus stinks, everyone was told about his secret shortly after Venus asks "Tell us what?"...his personality was revealed to be caused by the insanity from loneliness for 165 years because of his orbit, leading him to make imaginary friends out of asteroids in the Kuiper Belt...however, Neptune’s memory and sanity seem to be steadily improving...Neptune memorized all of the names of his moons - the only gas giant to do so." - S.B.W
