Legendary artist John Severin (Two-Fisted Tales) lends his pen to the second of four one-shots set during the Bureau for Paranormal Research and Defense's fight against the frog monsters. Series writer John Arcudi and Hellboy creator Mike Mignola take B.P.R.D. back to its roots with a classic horror story: a squadron of B.P.R.D. soldiers hunts down a nest of frog monsters on an abandoned battleship--only to become their quarry's prey.
