Turns out those pupulons are the most vicious invasive species of the universe. Made from radiation, it sucks the bone marrow right out of your bones. Its saliva is lead based and they shoot plasma out of its eyes. They also attach to any ship that gets close, make themselves invisible and multiply into infinity in space.

They also recently developed faster than light travel and are making themselves ready to invade the universe.

Even moopsy is scared of them.

Their tactic of using big eyes even worked on those other aliens.
