S.N.O.T.

As S.N.O.T. comes into play, you may stick it onto another creature named S.N.O.T. in play. If you do, all those creatures form a single creature.
S.N.O.T.'s power and toughness are equal to the square of the number of S.N.O.T.s stuck together. (One is a 1/1, two are a 4/4, three are a 9/9, and four are a 16/16.)

You may have S.N.O.T. enter 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.)
