Tecumseh (t) got lost in the anglepod as soon as he entered (ang2). He was able to call for help over radio though, so he drew big marks on the earth using a crayon (肀). His rescuers saw the sign soon afterwards from their plane and sent him mandarins (口), with a little parachute (广) attached to each mandarin. As Tecumseh received the first mandarin he was happily waving to the plane with his tang jacket (唐).
