Biography
After seeing the First Doctor on television, the trio decided to attempt to get his autograph at the studio. However, they were caught by the studio security guard Hoppit, and they hid inside a Police box nearby. After pressing a button, they accidentally travelled to the Stone Age, realising the box was The Doctor's TARDIS.

Exploring a nearby cave, they soon realised it was a Stone Age TV Studio, and they were chased away by a Stone-Age Hoppit. Returning to the 20th century in the TARDIS, they were again caught by Hoppit, and accepted there would be Hoppits anywhere they went. (COMIC: TV Terrors)
