Red arrows above battle droids

I've noticed that sometimes when I'm fighting a bunch of battle droids in the toybox they will have red arrows floating above their heads. Does anybody know what they mean? I've only noticed it with the Star Wars battle droids and not other kinds of enemies.

If you (or whoever made the toy box) used the marker creativi-toy, you can set it to mark enemies. I haven't used this in my own toy boxes, but I imagine that's what this is. Basically, it's pointing out anyone you want to fight.

No, it's definitely not that. I'm talking about a bunch of small red arrows pointing up that are animated and floating up around the heads of the battle droids. Is there a way to take a screenshot on the Wii U? Then I could show it.

I took some screenshots from my iPad:

I think that this is caused by the battle droid commander. Red "radio waves" come out of the commander's head, then the arrows show up around the other battle droids. I'm still not sure what effect it has on them though.

Oh, that IS weird. Never seen it before.

I think I once heard them say "calling reinforcements" when they displayed that effect.
