Level 3 in the Caves of Ordeal:
This level has level 150 monsters, an aura that decreases your stats by more than half, Geo Panels that disallow you to throw, and warps. They will usually cast Super Egg, which will damage your characters if they are grouped together or alone. create a White Dragon class monster. Their aura effect is immunity to non-Special (Element) Attribute Attacks. Because Super Egg is a physical Attribute Attack, the White Dragon class monster should be immune to the attack, thus losing no HP unless they physically attack you. Make at least three to five White Dragons, leveling them up to about level 100 to 125 to complete this level. Otherwise, level up Adell and his gang to at least level 120, dealing them the hard way. It is also recommended that you have at least two to three high level Beast Tamer human class to help the White Dragon class monster in Attack, Defense, Magic, and EXP. After killing all the "white chicken" monsters, bring out your main characters. Do not destroy the Warp Geo Panel, located near the No Throw Geo Panel, which is found on the sides of the "red chicken" monster. Let it warp you to the near top end where the "red chicken" monster is located. Move your characters in the panels that have no Geo Panel, then either throw a White Dragon or your main characters up there and finish the stage.
Napoleon Dynamite easter egg:
In Axel mode, Axel will learn a move called Love Dynamite. The description reads "I voted for Pedro", of course referring to Napoleon's friend who was running for class president.
The Lord Of The Rings easter egg:
The Elven Bow's description states that it was used by an elf in a quest to destroy a ring, referencing Legolas and the One Ring.
Quickly gaining felonies for party:
Usually only one character can move into the dark court panel in the item world. However, as long as all the characters move onto the panel in a single action, they all get the felony. The easiest way to do this is to have a number of human characters magichange with monsters and have the human characters pick each other up. After that, have the bottom character throw the others onto the dark court panel. Keep in mind that only up to 9 characters can be entered into the dark court this way, since the bottom character has to throw the others. All characters will get the felonies, but the dialogue of the prinny judge is determined by the character at the bottom of the stack.
