There are quite a few bonus costumes to unlock in Rayman Legends.
To unlock the bonus costumes, you just need a certain amount of Lums to purchase them from the Heroes Gallery.
I have noticed that some of the costumes cost different amounts on the WiiU compared to other consoles for some reason, so I’ve made two separate lists.
Flaming Teensy – 440,000 Lums
Globolk – 350,000 Lums
GlobTeen – 20,000 Lums
Glombrox – 75,000 Lums
Ninja Teensy – 280,000 Lums
Plumber Globox – 28,000 Lums
Plumber Ray – 9,000 Lums
