Percival Shacklehorn, a wizard who went on expeditions to hunt magical creatures, owned a tent charmed to be larger on the inside than it appears to be on the outside.
While appearing simple on the outside, its interior included columns, a staircase, multiple armchairs, and a Grandfather clock.
Returning from the Alps, he inadvertently transported both a Mountain Troll and the Muggle monster hunter Laura Thorn, who both had sneaked into his tent, to the Leaky Cauldron in London.
Mathilda Grimblehawk noted that Shacklehorn's failure to protect his tent with Muggle-Repelling Charms constituted a breach of the International Statute of Wizarding Secrecy.
