how can a player's stats change so much so fast?

i'm in a $3/$6 hold 'em ring game on pacific.the bad player to my right has been at the table for a while, so i have about 60 hands on him. i notice that he is a fish icon (loose/passive-passive) and make a good fold on the flop with top pair in a decent pot when he raises a bet.four hands later, i notice that his icon has changed to a gambler (loose/aggressive-passive).five minutes later (less than ten hands), he has changed into a sad face (semi-loose/aggressive-passive).just now, about six hands later, he is a bomb (semi-loose/passive-aggressive).i can understand him going from loose to semi-loose, no big deal, but how does he change from passive-passive to aggressive-passive to passive-aggressive in the span of about 20-30 hands?aseem

cause 60 hands isn't much, and their play in those hands will dictate the changes, since it is such a small sample size, you'll see big swings just based off of them folding more and getting more aggro in spots
