to quote Norman:
Lord Foul wrote:Norman does as bidden, writing a full account of all that he has witnessed. However, as he really is a rat and has no allegiance other than to himself, he thinks to try to hedge his bets. Within the account he includes extra details about the wood creatures, their numbers, abilities and apparent weaknesses, which he leaves out when he reads it back to the Queen. He also adds a note that says "When you come look out for a human apparently helping the wood creatures, for I will help you to deal with them."
He thinks that he is giving himself the best chance to survive, whichever side proves victorious. Charmed he may be, but his nature dictates his self-serving actions.
So that would include the events he witnessed, The numbers and types of threats(The large viny creatures, the little men with spears, the wooden dogs, the lieutenants, and Queen Ainecotte herself), how the little woodmen erupted from the corpses of the dead(very different than what happened to ET). I believe the creation of the large viny creatures was mentioned at least once(groups of the little men chanting and summoning them), the creatures immunity to wooden weapons and weakness to fire, and the toxic sap they smear on their weapons.
