"Do not fear, I only vant to drink your Mango juice."

Pteropus vampyrus -- Malayan Fruit Bat, a score of them,
6-foot wingspread and all, at the Oakland Zoo.

Misnamed -- they eat only fruit, but, to be fair, this one, in particular, sure does look a lot like he could be the Count himself, cape wrapped around, being charming with a Transylvanian accent.

If you're within driving distance, check them out.
There are also 11 Island Fruit Bats in there with them, smaller fellows -- wings only 4-feet across, but it's the only place west of the Mississippi to see either species.
