Dimensional Hop for very big creatures

[Particle_Man]

Let’s say I am a colossal creature with one level of ardent and the dimensional hop power. It lets me teleport 10 feet but I already take up more space than that. Do I still only shift over two squares, mostly taking up the spaces I took up before, or do I get to pick the part of me that appears in the first square and then fill out the other spaces adjacent to it as I see fit, in effect moving more than two squares?

You move two squares exactly. So much of your mass is going to be the same place as it was.
