Trouble with Sleem

[kadrzys]

hi all, I was playing demo version till I realised everything it's done as for demo. So I bouhgt full version and I find this game amazing but.. Spirits of Rage.. In demo I got Chest with Zerock and Sleem obeyed to me. In full I've completed Zerock task (easy battle) and I'm trying to get Sleem "my friend". But how can I feed him? Little info says: "Sleem will gobble up poisonous Swamp and Royal Snakes and Poisonous Spiders form your army.." I've been in whole Darion and there's no Swamp or Royal Snakes or Poisonous Spiders to buy:/ I found some spider and snake eggs but I got only Snakes and Cave Spiders from them. I really need this Evil Shoal thing for my warrior:/ any clues?
