Creature known from the Dr. Seuss story "How the Grinch stole Christmas", where it's purpose is pretty much the same as the (poor) Christmas turkey - to be eaten.

In the motion-picture by Ron Howard and with Jim Carrey as the Grinch, it seems to have eight legs.
And he... ...HE HIMSELF...! The Grinch carved the roast beast!

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
Billionaires are having a dick swinging space race while the earth experiences record breaking heatwaves that cause sea creatures to literally cook inside their shells. We need planetary quarantine.
