The Secret Sheep Level was a location in Tibia which used to contain several Sheep and a Black Sheep. This hidden cave was designed and mapped by Knightmare.
Back in the day, the Secret Sheep Level was discovered by Pepelu and Halfhigh (Original pictures at the Red Rose guild forum). CipSoft had no idea of its existence and found out the place was being abused to make runes and/or train while being AFK by using macros. Therefore, they removed the place. It was located in the Edron Rotworm Cave in Stonehome, which is now a Bog Raider Cave.
