I have no idea whether there'd be a place for this, but I'll take a shot and suggest it anyhow.
A trio of hanging bats that get alerted by player (possibly also enemy?) movement, and when startled shoot downwards in a /|\ pattern to attack the target. Could be a challenge for scenarios where the player will have to plan out a time-sensitive path to avoid other enemies whilst simultaneously making sure not to alert any bats/take advantage of their movement patterns. Which manner of vore would be involved, I'd just leave up to your discretion. Maybe splitting up various types between the three based upon whichever caught you would work.
