I made me a monster bat/Gargoyle in neon colors because I wanted one.

This monster feeds on stomach acid. When he catches someone he will force his claws into their mouth so they swallow the ooze always dripping from them. The ooze will numb their throat and mouth so they do not gag, and also causes them to overproduce stomach acid. He will then slither his tongue down their throat, push out the barbs on his tongue to trap the acid, and then pull it back up. He will continue to do this until he has eaten his fill. The overproduction of acid lasts a few minutes and the numbness can last over an hour. In extreme cases some people will overproduce stomach acid for almost an hour, but this is very very rare.
