Tangerine

Tangerines were a type of fruit found on Earth. According to a dream version of Santa Claus, tangerines were his signature gift. The Twelfth Doctor, on the other hand, claimed that, "no-one likes the tangerines". After the Twelfth Doctor and Clara Oswald resumed travelling with each other, a tangerine was left on Clara's windowsill. (TV: Last Christmas)
