Giant Vampire Bats

Giant Vampire Bats are creatures portrayed in 3. The Latin name for the common vampire bat, Desmodus rotundus, is written beneath a sketch of a bat on the same page.

History
There is one seen behind Grunkle Stan when he, Dipper, Mabel, Wendy and Soos gather around the campfire during the theme song.

In "Tourist Trapped," when Dipper is going through some of book 3's pages there entry is briefly seen.

In "Land Before Swine," after Soos kills the Fairy there entry page in 3 is seen again.

Appearance
As stated in book 3 they have a ten foot wingspan, which is longer than the average human height of six feet. They seem to resemble a very large Common Vampire Bat. Besides the size, the only real difference is the large, hairy tuft on its head, which other vampire bats lack.
