What does "all stealthy like" mean? And is "like" a filler word here?

"Stealthy" means to be sneaky or to move quietly in a way where someone is trying to not be seen or heard. The word "all" here means "really", "very", or "so". So "all stealthy" means really stealthy. "Like" is used here to mean that it resembles or is similar to. He uses this to express that he is imitating the action of being stealthy, and he does this by lowering his voice and talking quietly and slowly.
