IKEA

IKEA was, according to the Twelfth Doctor, a "painfully strange shop" on Earth.

When the Shadow Kin invaded Coal Hill Academy in search of Cabinet of Souls, which they referred to as just "the Cabinet", the Twelfth Doctor suggested an easy way to procure one would be to go to IKEA. (TV: For Tonight We Might Die)

When the Thirteenth Doctor explained to her companions how psychic paper was made, she informed them that the essence of the psychic trees used passed on to "wherever trees go when they die", before Graham O'Brien jokingly suggested that they passed on to IKEA. (PROSE: Paper Moon)
