I disagree.
Most puzzles in Monkey 2 are logical, which doesn't mean easy at all.
When Wally gets kidnapped, you feel like you need help from the voodoo lady and that's the reason why you go to the swamp.
At least, this is how I always felt it.
Monkey 2 is one of the few adventure games with very hard puzzles that feel logical once you solved'em.
What a masterpiece.
