“Hey, everybody! Let’s Disco!”
The Disco Dude has traveled back in time to relive the days of disco dancing, bell-bottom pants and the very first LEGO Space sets. He can’t help but love it! Whenever he hears a disco beat and sees the big disco ball lights start flashing, he gets caught up in the music and just can’t stop dancing.
And what’s more, it’s his love of disco is contagious! Wherever the Disco Dude starts dancing, everybody around him can’t help but join in on the fun. Pretty soon, it’s all one big ‘70s disco dance party!
