I did this a while ago, but I believe you need to step on them in a certain order. There are 6 tiles total with 3 different animals on them. You need to walk over each animal once in a certain order. I don't remember the order, sorry.

We proceeded that way:
My friend stood on one symbol , and i tried the other ones, then she took another one and i tried the others again. Doing this , we saw that some of the symbols i moved on lost their "pillars" of light. we were able to light off all symbols but scorpions.
As long as i was the only one on the scorpion , nothing happened but as soon as she moved on the 2nd one , both of them went off and the boss and minions popped. we killed them easily and get both skillpoint and achievement.
it's still not the right way to make them pop but i hope it'll help in understanding how this event work.
