Coal Hill Year 8 Gifted and Talented Group
From Tardis Wiki, the free Doctor Who reference
Coal Hill Year 8 Gifted and Talented Group was a student organisation at Coal Hill School in the early 20th century. Its members included Maebh Arden, Samson, Bradley and Ruby.
Danny Pink and Clara Oswald took the Group on a camping 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 Doctor's help. Danny assisted by keeping an eye on the group while the Doctor and Clara investigated the situation.
