yes the terrorist attempt was undertaken by a "GIANT HALF CHICKEN HALF SQUIRREL"
The giant half chicken half squirrel steals either teeth or money from children as they sleep in order to build some kind of giant nest for its' genetically superior and potentially dangerous offspring.
It is also known that this creature would also have atleast a mild understanding of algebra.
The half chicken half squirrel would most likely be about three to four and a half feet tall.
His large beak is probably detachable and works as a floatation device.
