Lego built a new character into its lineup — releasing its first disabled figure following a social media campaign that asked the company to have more diverse options.

A mini male figurine in a wheelchair accompanied by a helper dog was spotted at a London toy fair Thursday as part of Lego’s Fun in the Park set.

The move comes nearly a year after a Change.org petition called #ToyLikeMe that asked the company to include minifigures went viral — garnering more than 20,000 signatures.

“We’ve got genuine tears of joy right now,” Rebecca Atkinson, who started the petition, wrote Tuesday, adding that the company “rocked our brick built world.”

About a year ago, she wrote a lengthy post imploring Lego to be more inclusive.

“Please, Lego, put some wheelchair vroom vroom into the toy box and help generations of kids, (both with and without disabilities), grow up with a more positive attitude to human difference,” she wrote.

The toy set, which includes 14 minifigures and one little baby as well as a carousel, picnic bench and lawn mower, is set to be released this summer.
