WotLK I'm looking for the name of a specific item - I saw it used on icecrown - wotlk

I was in Orgrimmar on my paladin, and came across what was very OBVIOUSLY a PvP lure.. a bunny sitting in the middle of the drag, with a PvP flag on it... I continued watching and eventually a newer player got curious enough, and hit it... and surely enough... they flagged themselves... and thus ensued a moderate-scale PvP battle between 3 rogues vs the newer player (DK), me, and a hunter.
We lost... lol..
That being said, for the life of me I cannot remember the name of the bunny, and I've searched around and cant find anything relating to an item that can flag other players. Does anyone know what this is? The rogues who used it were alliance

Best guess is it is some sort of target dummy made by engineers. There are a few of them
