This spell summons to your side one Purple Worm with the giant Creature simple template.

Creatures cannot be summoned into an environment that cannot support them. Creatures summoned using this spell cannot use spells or Spell-Like Abilities that duplicate spells that have expensive material Components (such as wish).

The purple worm's Alignment matches yours, regardless of its usual Alignment. Summoning these creatures makes the summoning spell's type match your Alignment.
