Klonoa Phantasy Reverie Series

This trophy is unlocked in Klonoa 2: Lunatea's Veil.

The Chamber o'Fun is the first of the game's two extra levels which can be unlocked when you collect six Momett Dolls for the first time, when this happens, you will need to return to the Momett House, where Momett will tell you that a new attraction has opened for Klonoa to enter and test his skills.

This is very straightforward if you know how to time your double jumps correctly and understand the basics of how the Klonoa games work since the mechanics featured throughout the first six levels will be present in this level.

Be warned that in the final part of the level, you should try to appropriately space out your distance between yourself and the ceiling of each floor when using the Erbil's unique double jump mechanic. You can also use Support Mode to have a second player help you out with the Support Jump in the event that you're having trouble doing this on your own, but be sure to use it wisely since there is a cooldown whenever the aforementioned mechanic is used. (Details on Support Mode can be found in the Roadmap)

It should be noted that, unlike the first game's extra level, you cannot lose lives in any one of the two extra levels in the second game. This makes it much fairer and easier to go through without all the needed stress of losing a life while playing through these levels, regardless of difficulty. You will also unlock this trophy once you complete this level for the first time. A video of this level can be found below:
