The enemy of my enemy. I love this topic. Borrowing from earlier threads I've seen:

• Abomination versus Sea Serpent (Abomination)
  
• Troll versus Sea Serpent (Troll)
  
• Seeker versus Deathsquito (Seeker, but more Deathsquito will eventually get the seeker)
  
• Troll versus Fuling village (Fulings)
  
• Fulings versus Growths (Fulings)
  
• You are being hunted pack led into Fuling village (Fulings)
  
• Seeker versus Lox (Lox)
  
• Stone Golem versus Drakes (Golem, but it seems to never end).

I've got busted screenshots at present and seems to have started when IGS put the cloud fixes in last year. I'll need to get that fixed so I can get some captures.
