I was helping in Cool Ranch,(Castillo Sapo) and in the Aquillan Labyrinth yesterday on my Buccaneer. In a number of fights, my pink marshadillow seemed to stay by my side in the same way it usually follows outside fights. When I made a move on the enemy it followed along. If the fight animation appeared where the Dillo was, the dillo flickered off then back again. When my pet officially joined the fights, there appeared to be a couple of them, one in it's own battleboard spot, and one next to me. The first couple times I saw this ghost pet, I thought 1. my pet had joined the fight when I wasn't noticing and 2. Does someone else here have a Marshadillow too?

That sounds about right. In the Castillo, as soon as the first pirate went through the door, dialog happened and I was stuck. As soon as I went through the door, I was pulled in. In the labyrinth, a couple of us kept getting pulled in from a long way away.
