Observe with me now, the mysterious bump in the, so called,"green space," on the Peoria, Illinois riverfront. Discovered in 2018 by unsuspecting Caterpillar tractor operators, who have now since disappeared, with no trace. 
Scientists from around the globe have utilized state of the art technology to decipher the mystery beneath the surface of the pulsating mound, but to no avail. 

Any industrial type of diamond tipped drill, explosives, or even lasers have yet to penetrate into the unknown secrets of the indestructible mound.
Could it merely be a natural formation that  has a perfectly logical explanation, or a buried spaceship...the first of an OTHER WORLDLY ADVANCED FORCE, intent on the destruction of the earth, enslavement of mankind, and turning us into shish kabob?!! 

Renowned astrophysicist, Elroy Jetson,  has theorized that this "bump"could be an interdimensional, transitional, uni-directional,  quark of gargantuan proportions, that is basically harmless if we just stop messin' wit it! 

In conclusion, we are told not to worry about things that go bump in the night, but what about a "bump" in the day?
