The Coal Hill Year 8 Gifted and Talented Group was a student body at Coal Hill School in the 2010s. Its members included Maebh Arden, Samson, Bradley and Ruby. Each student had some kind of disability; Maebh heard voices because she wanted to find her lost sister, Bradley was aggressive, and Ruby was dense.
Danny Pink and Clara Oswald took the Group on a sleepover trip to London Zoological Museum. To their shock the next morning, trees had grown all over the world overnight. Forced by Clara, Danny helped lead the group to the TARDIS to get the Twelfth Doctor's help. Danny assisted by keeping an eye on the group while the Doctor and Clara investigated the situation.
