After centuries of human failures, dolphin scientists have finally figured out a way to contact extraterrestrial lifeforms.
Just as they made contact, dolphin seismologists detected TREMENDOUS WAVES threatening the imminent collapse of the Earth’s core.
Luckily, contact with the extraterrestrials proved friendly, and they have sent forces to evacuate all life forms from Earth using their tractor beams.
The only issue is that humans fear the aliens, and must be out-smarted and rounded up in order to be safely transported.
