Blue Alien

This unknown species were a group of Humanoid Space faring Aliens that kidnapped Eiffel 65 singer Jeffrey Jey during a music gig and took him to their homeworld in the Blue music video.

The kidnap forced the other two band members - Maurizio Lobina and Gabry Ponte - to fly after the aliens in their own ship to try and rescue Jeffrey - with them fighting the aliens who tried to stop them using dance moves and energy-based attacks.

Although Blue Eiffel did rescue Jeffrey Jey and escaped their planet, they had a change of heart after the Blue Aliens asked them to come back and later played the rest of their gig to the alien audience.

Biology
