Collin's thrown stone remains ineffective, so he sends out his Sandshrew. The snake in the small tunnel seems to bite Maia again and the one circling above ground bites Rhea as well. The Sandshrew seems shocked at the ferocity of the bite and is unable to follow Collin's command.

Maia gets hit for 12 Damage. Rhea gets hit for 18 Damage and is flinched. You have line of sight for Rhea, but not Maia. You can command Maia to attack because Rhea can't follow your commands.
