Look, if you have wide scan, place yourself in I-7, Top Center part of it, just before you reach the river. Look in Wide Scan, Spipi's place holder is in-fact, the 3rd crawler in the set of 3, between the group of bees and a Goblin Thug. You know its the PH, if the 3rd crawler pops behind the other side of the hill from the tower, by the river.(where J-6 and K-6 intersect)
The PH can pop in a few other locations away from the river, for instance, on the other side of the hill, this is normal. Just kill the PH and within an hr Spipi will pop. When you know it's TOD, start killing again about 30-45min after. If you do that, it's Guaranteed to come within 5min-45min, making it a 45min-90min pop. Good Luck!
