Immoth (CR 9 creature, MM2 pg. 127): "Ice Runes (Sp): "Any spell an immoth has prepared can be inscribed on an ice nugget. The creature can trigger the spell contained in such an ice rune as a free action. An ice rune remains magical until triggered by the immoth. Each immoth has at least 3d4+12 ice runes embedded on its body."
So it can cast up to 24 spells, all as free actions, in the FIRST ROUND.

Brownies as Characters
Brownie characters possess the following racial traits.
-- -6 Strength, +10 Dexterity, +2 Constitution, +2 Intelligence, +2 Wisdom, +2 Charisma
--Tiny size: A brownie has a +2 bonus to Armor class and attack rolls and a +8 bonus on Hide checks. A brownie uses smaller weapons than humans use, and his lifting and carrying limits are half of those of a Medium character.
--A brownie's base land speed is 30 feet.
--Darkvision out to 30 feet.
--Low-light vision.
--Calm Animal: As a free action, a brownie can calm an animal. The power is similar to a calm animals spell, except that it works on a single animal within 30 feet. An animal that has been affected or has made a successful saving throw against this power cannot be affected again for one day. The caster level for this power is 7 + the brownie's character level. The save DC against this power is 14 + the brownie's Charisma modifier. This is a supernatural ability.
--Spell-Like Abilities: A brownie can use the any of the following, each once a day: confusion, dancing lights, daylight, dimension door, protection from evil, ventriloquism. Saving throws are 10 + spell level + the brownie's Charisma modifier. The brownie's caster level is 7 + the brownie's character level.
-- Evasion (Ex):If a brownie is exposed to any effect that normally allows it to attempt a Reflex saving throw for half damage, the brownie takes no damage with a successful saving throw. If the brownie gains a class level that gives it the evasion class feature, the brownie gains improved evasion instead.
-- Hide in Plain Sight (Ex): In areas of dim light, tall grass, or heavy undergrowth a brownie can use the Hide skill even while being observed and without having anything to actually hide behind. This ability does not stack with the hide in plain sight class feature.
-- Uncanny Dodge (Ex): A brownie retains its Dexterity bonus to AC even if caught flat-footed or targeted by an unseen foe. However, the brownie still loses its Dexterity bonus to AC if paralyzed or otherwise immobile. If the brownie gains a class level that gives it the uncanny dodge class feature, the brownie gains improved uncanny dodge instead.
-- Wild Empathy (Ex): A brownie can improve the attitude of an animal as a druid does. The brownie's bonus on wild empathy checks is 7 + the brownie's Charisma modifier. If the brownie gains levels in a class that has the wild empathy class feature, the brownie's bonus on wild empathy checks is 7 + the relevant class level + the brownie's Charisma modifier.

-- Automatic Languages: Common, Halfling, and Sylvan.
-- Bonus Languages: Draconic, Elven, Giant, Goblin, and Gnome.
-- Favored Class: Expert.

The color spray spell is actually better than most people think (and most people think it's pretty damn good) you see on page 173 of the player's handbook where they describe the sub-schools of magic under pattern you can see:
Like a figment, a pattern spell creates an image that others can see, but a pattern also affects the minds of those who see it or are caught in it. All patterns are mind-affecting spells.
This means that targets outside of the area of color spray are still affected by it if they can see the effects. This rule also applies to Hypnotic Pattern, Rainbow Pattern, and Scintillating Pattern.
