Glorp

The Glorp were a species native to the planet Plorp. According to the Thirteenth Doctor, they were fantastic engineers.

They helped the Doctor in fixing her TARDIS, which was malfunctioning after Lizzie accidentally dropped a peanut butter sandwich into a slot in the control panels. Lizzie befriended the smallest of the Glorp, Blorp, who bonded over their shared love of peanut putter sandwiches, and Lizzie smuggled Blorp home in her rucksack. (PROSE: The Runaway TARDIS)
