Here is the official explanation of what the Activity is, which can be found on the same page where submissions should be uploaded:
Create a unique minifigure! Express who you are by creating the most individual minifigure you can think of. A doctor with a clown’s wig? Or an elephant with panda legs? YOU decide! Tell us in the caption what “Free To Be Me” means to you!
As the description makes clear, this is a simple one! There is no size restriction or specific shade of blue mentioned, the only criteria is to use blue LEGO bricks.
This is part of a series on LEGO Ideas that gives little tasks for builders to get involved with – there are no prizes, they are just a way to get involved with building something quick for fun. Each challenge is intended to be something quick and fun, unlike the more in-depth building required for a competition or product idea.
The deadline for this Activity is January 21 at 10.00am CEST.
The last LEGO Activity asked fans to construct something only using blue bricks.
