Defeating the Demon Jaguar
If he enters into a rage (running, leaping at you non-stop, giving you no chance), keep on super running either left or right until he finally stops. When he does, kick him very quickly. Repeat this process to destroy him. This works about every four or five times. If it does not work, start running behind him in circles when he runs in circles. Try to cut him off and kick him.

Defeating Pusca's minions
Instead of hitting or kicking the pillars towards them, you can get your pick axes out and spin around by pressing [Down] then repeatedly pressing [C-stick Up]. Note: You are invincible when doing this, but you still need to be careful when Harry becomes dizzy. Quickly press [A] to stop being dizzy and start spinning again before they resume shooting at you.

Entering the Monkey Temple level
On each of the opposite ends of the closed door, there is a picture of a monkey inside a ring of fire. Light the bowls in front of the pictures to enter the Monkey Temple.

The explorer at the Flooded Courtyard
When you have received your pick axes, go through the Jungle Trail until you reach the hole that leads to the Flooded Courtyard. Go around it to the mesh of roots, and roll under it by holding down [R] and using the [C-stick] to control your movement. Get past the scorpions and use your pick axes to climb up the ice. On the ledge above the ice, you will see a hole, in which is the shortcut to the Flooded Courtyard. Roll under it. When you arrive at the Flooded Courtyard, to your right you will see the explorer in a cage. On the bottom ledge there is an idol.
