It has been a long time since I last painted some Dr Who Tetraps. In fact not since 18 January 2021!

Tetraps are a sapient mammalianoid species from the planet Tetrapyriarbus. They are bulky, hirsute, bat-like humanoids with four eyes positioned around the head: one on the face, one on the back, and one on each side.

They also have four ears – the upper pair facing forwards and the lower one facing backwards – and membranous flaps under their arms, which probably represent vestigial wings.

Tetraps are not able to fly (at least not under the Earth-like gravity pull of Lakertya) but do hang upside down on ceilings much like regular bats. They have a tubular tongue which can be used to inject a paralyzing toxin and to feed on blood plasma from their victims.

Time for Guru to go back to his “Time and Relative Dimension in Space”.
