Tracking Stepping on Cragmaw's Blood Ticks

Hi friends –

It doesn’t appear that there is a single event that fires (CLEU or otherwise) when someone successfully steps on a Blood Tick (larva). I thought it’d be fun to keep track as a sort of competition, like my friends do with Explosive Orbs and Afflicted, but I don’t believe there is any way via the WoW API/Events to know that this occurred.

Any thoughts? It appears Cragmaw is a Vehicle- unit, which is interesting. If anyone can think of a really clever way to track these step-ons, I’d appreciate it. I’m simply walking into Underrot (Normal) stealthing right up to Cragmaw, then letting him hit me until he Charges once. I then step on a few blood ticks and see what events I can observe, and vanish.
