You may be looking for space buggy.

Acquired on the planet Kandro Four by the Eleventh Doctor as pets for travelling companion Decky Flamboon, a pair of space bugs turned out to be time sensitive. A rough ride in the TARDIS through the Time Vortex caused them to grow. After running amok in the city of Dubai, they continued to grow and evolve. Fed by the time energy, they developed speech and wisdom before leaving the planet with their new found mental powers that allowed them to teleport to somewhere where their appearance was less frightening.
