Throw characters through No Entry panels or tall terrain

As long as the obstacle is only one square thick, you can throw through it. Stand next to it and lift a character, then extend your throw through the obstacle. Retract your throw range (toward the thrower) and press X at the same time. There is a "sweet spot" to do it right, but because there is no penalty to missing it (you just get an error sound) you can keep extending and retracting while mashing X until you throw straight through the obstacle.

Land of Carnage

To unlock the Land of Carnage (a mirror world of every level with super difficult enemies), collect all 16 treasure maps from the different pirates in the Item World.
