Rayman Legends

You will get this achievement after completing the last level in the chapter "Olympus Maximus" which is called "Dragon Slayer". This achievement is unmissable!

To unlock this particular stage just complete all the other levels in the "Olympus Maximus" painting. If you are still short of Teensies you can just try to clean-up the levels you have already done (refer to the specific solutions here on TA to find every captured companion etc.) or you can switch to another painting and clear out some stages there. It is completely up to you.

Dragon Slayer is one of the musical levels in the game. You will most likely have seen one before in other paintings like the "Castle Rock" stage in the "Teensies in Trouble" painting.
If you have played one of these stages before you know what to do. Listen to the music and jump, punsh etc. whenever the music changes it's pace.
Since this is a musical stage you only have to worry about three captured companions in within the stage. All of them are more or less right on your way so you should have no problems finding them.

If you get stuck on a specific part in the level or if you struggle finding all you captured friends refer to the video below

Hope this helps you guys :-)
Any improvements? Please let me know in the comments! .

"Dragon's Slayer" is the final painting under Olympus Maximus painting. You do need to beat the boss in the Olympus Maximus painting under "A Cloud Of Darkness" before entering the musical. It is one of the challenging musicals, so bear that in mind but running, jumping and attacking in the rhythm is so much fun. There are also three teensies to collect in the level (which aren't that hard to collect). Once you've completed the mission, the achievement should pop! Have fun!
