Yeah, you lay down 1 Stealth Rock layer and 2 Toxic Spike layers together. I believe Nidoking and Nidoqueen can learn both (Toxic Spikes from Pre-Evolution and Stealth Rock from TM). Foretress can learn Stealth Rock, Toxic Spikes, AND Spikes (lol). So Foretress could set this up:
1 Stealth Rock Layer
2 Toxic Spike Layers
3 Spike Layers
But then again, Rapid Spin ruins all of that, so be careful if you use a strategy like that.
