From Quake Wiki
Spawn (also known as Tarbabies) are annoying little blue blobs that bounce around, ricochet off walls, and hurt you if they smack into you. They don't take long to kill, so don't fire at them unless you're at a safe distance. When they die, they explode like a rocket - and hurt just as badly. They will come after you pretty quickly, so back up as fast as you can and fire once you know you're safe. Don't bother strafing, as they have to be near you to hurt you.
"A merrily bouncing blob as dangerous to kill as to ignore. Blech."
