3 stars - Mog Dance: A small Mog restores the party's HP, MP, and nagative satus effects.
3 kings - Toy Soldier: Six toy soldiers appear as guests for the remainder of the battle.
3 bars - Summon: Cait Sith uses a spell at on a randomly chosen foe.
3 Mog - Transform: Cait Sith turns into a giant, gaining more hit points and attack power.
3 Hearts - Lucky Girl: Party's hit percentage increases for the rest of the battle.
3 Cait Sith - Instant Victory: This incredibly rare slot combination kills all enemies on the screen. This works even for bosses, but is very hard to get.
2 Cait Sith and a bar - Death to all: The party is instantly killed. Don't worry, much like Instant Victory, this is very rare.
Anything else - Toy Box: A toy box will appear and do a small amount of damage to a random enemy.

Cait Sith is difficult. His equip set would be much like Reis's.

Anyone else?
