After expanding TribalStack Tropics, Rampo will move in at the top of his temple on the left side on the map. All you have to do is use your roll to avoid or jump over the logs to get to him. Once at the top, avoid his fire breath and then knock out his teeth. Afterward, he will blow you back to the bottom. This will repeat twice more until he is defeated. Remember that there are 4 butterflies at the bottom and one in the middle of the ramp to refill health or stamina. Power extenders and/or the tonic that reduces the cost of roll are useful.
