I think it'd be funnier, as well as more accurate to the mythology, if instead of using the generic recharge mechanic it required a (difficult) Strength check to lift its head .The Catobelpas was ported from earlier editions, where sudden death was far more common.
It is also based on a mythical creature, described by Pliny the Elder (he who died at Pompeii) that was said to have gaze (or bad breath) that could kill instantly or turn to stone.
It was probably a somewhat garbled account of a wildebeest.
