Underfood Stampede!

You weave and veer between the legs of your enemies, causing them to fall over as you race across the battlefield. Stride twice, each in a straight line. You can move through the spaces of creatures that are at least one size larger than you, attempting to Trip each creature whose space you enter. All attacks count toward your multiple attack penalty, but the penalty doesn't increase until after you've made all of them. You can attempt to Trip the same creature only once in a single Underfoot Stampede!
