Klonoa Phantasy Reverie Series

Story related. Cannot be missed.

This trophy is unlocked in Klonoa: Door to Phantomile.

Rongo Lango is the first boss that you will fight throughout the course of the story at the top of Bell Hill at the end of Vision 1-2: The Diva and the Dark Spirit ~Gunston Mine~.

This boss fight is fairly simple, with its weak point being its back, so be sure to jump while holding a Moo and throw it whenever you see the chance to attack it. The first wave will have it performing high jumps to approach Klonoa as a means of attacking it. You can thankfully walk below it in order to attack it from behind, but keep in mind that it will rotate in your current direction whenever you try to get near it from one side to another provided that it doesn't jump to prevent Klonoa from attacking it from behind.

Once you have dealt two hits against it, it will gain two new attacks alongside its behavior of jumping towards Klonoa:

• The first of which has it stomping its tail on the floor in Klonoa's current direction to cause a quake that travels in a circular motion while aiming toward him.
• The second will have it create a rainbow shockwave ring around it to attack Klonoa as it travels from its current position and extends past the arena. 

You can dodge both of these attacks by jumping over them, but be sure to time these jumps correctly when doing so, especially while holding an enemy and approaching it once there's an opening to throw the current enemy you're holding to its back.

Once you get its attack patterns down and know what to do when fighting against it, you should be able to defeat this boss with ease.
