The storm copies enter the battlefield one by one, followed by the original spell. Each of them enters the battlefield with a number of +1/+1 counters equal to the number of Oozes you control as it enters the battlefield. If you don’t control any Oozes at the start, the first one enters with no counters, the second one enters with one counter, and so on.
