Sebastian Bradley was diagnosed with brain cancer in 2016.
"He's had a lot of surgeries," Sebastian's father Shane said, "He's gone through radiation, he's gone through chemo."
While he was going through chemo therapy, one thing that brought him comfort, was playing with Legos, so he started Sebastian's Lego Club, an organization that donates Legos to children at Oishei Children's Hospital.
"(It's to) provide kids who are just like him, you know that are in the hospital a lot, provide them with something to do."
On Friday night, Sebastian's Lego Club held a donation event at Sebastian's elementary school Forest Elementary in Williamsville. It's an event that helps show the elementary students what giving back is all about.
"This is what we teach kids beyond the classroom," Principle Keith Wing said, "this is the character and the community and the culture that we teach."
