Multiple hedgehogs - Index out of range error

[alexdriedger]

Here's the test to reproduce it

    def test_multiple_hedgehog(self):
        team1 = Team([Pet("fish"), Pet("hedgehog")])
        team2 = Team([Pet("elephant"), Pet("hedgehog")])

        test_battle = Battle(team1, team2)
        test_battle.battle()
