You may have S. N. O. T. enter the battlefield stuck to another creature named S. N. O. T. If you do, all those creatures form a single creature.
S. N. O. T. 's power and toughness are each equal to the square of the number of cards named S. N. O. T. stuck together to form it. ( One is a 1/1, two are a 4/4, three are a 9/9, and four are a 16/16. If you manage to get -1 S. N. O. T. s stuck together, it's a 1/1)
