Pepper carries a security blanket around. He has been known to take naps, even in the middle of softball or basketball games.
He is kind of a coward or dependent, he's the sort of person who wants attention, he's also a crybaby and a vengeful person, for example he pretends his blanket is missing and blamed others for stealing his blanket, as a payback for the ones who blamed him before.
However he's just an innocent child who just wants some nice attention from his friends, He doesn't like to be blamed on.
