- “You think a Tahval demon leaves a hefty security deposit?”
- ―Wesley[src]
"Tahval Demons" were an tentacled-like, parasitic species of demons who left eggs in abandoned or non-occuped houses. Apparently, their metabolism is constitued very quickly, allowing them to mature in a matter of hours. This defining characteristic prompted Cordelia to call one of the Tahval spawns as "Big Baby".
