After you move, if you are in the air and your Creature Base overlaps one or more Creature Bases that are smaller than yours, you may discard this Upgrade to crush those Creatures, ignoring all Creatures of your size or larger. You and the crushed Creatures must remove your altitude tokens, receive Ground Tokens, and then cannot change altitude again for the rest of the round.

Make a 5 Dice Attack against each Creature that you crush, and then move your base backward along the top of the template until it no longer overlaps another Creature. You may still attack normally during the Combat Phase.
