Dungeon Keeper 1 hidden, bonus level walkthrough, from level 8, Tickle ( RUS)

This walkthrough has my voice commentary in russian but knowledge of russian is not a must in order to understand how to beat this level. I pass Horned Reaper (10) from previous level (level 8, Tickle) in order for him to assist me in passing this level. I do not know ways to beat this level without transfering Horned Reaper (or any other unit strong enough), but with Horny this level is passable, although very difficult. By the way, I could not find any walkthrough for this level neither on Y
