i have spawned my sens once..it was amazing how the eggs scatter and sticked to the plants.unfortunately,only 1 hatched and died after 3 days.
Mr. Terryr here in mfk teached me how to breed em.he showed me a link from another forum,there was his posts on how to breed polys.the dude was amazing.unfortunately,i think he is no longer active here in mfk,and the his message to me with the link was deleted when mfk had a server down on 2009 i think.
When the potm for polys was still active,his entry was actually a polys' egg.
