I'm guessing each of the birds will peck your eyes out, the frog will emit a liquid that causes instant paralysis, senility and incontinence, and the Thylacine tiger, well that speaks for itself? Are the Budgerigar being exported to other countries as sleeper cells, ready to peck out the owner's eyeballs as soon as @sirknight issues the keyword into the receiver implanted in their brain? Very cunning!
