Princess Hentopet's Art

 was an art gallery used by Hentopet and Sheeq to try to attract the attention of an alien in 1974. Although it appeared to be made of regular building materials, it was actually a temporary building made out of sand.

Hentopet and Sheeq populated the gallery with people who had been turned into sand sculptures by Bubastion's powers. It was scheduled to be open from 8 July to 5 September.

The Tenth Doctor and Martha Jones became interested in the sand sculptures and visited the gallery. Once Bubastion realised that the Doctor would be a perfect alien for the Pantheon's plans, he no longer had any reason to continue supporting the gallery. All of the sculptures turned back into people and the gallery collapsed into a pile of sand. (COMIC: Agent Provocateur)
