Skateboard

A skateboard, also known simply as a board, was a long board with four wheels that could be easily carried and used as manually-operated transport.

Danny received a skateboard as a Christmas present. As part of the Eleventh Doctor's plan to reprogram the Zentrabots, Danny collided his skateboard into a Zentrabot. The Doctor later rode this skateboard to the holding pen containing children held hostage by the Zentra. (COMIC: The Zentrabot Invasion)
