At the age of nine, P.B. Jellystone, now a very wealthy, eccentric industrialist, had discovered the crash-landing of a purple meteorite near his family's backwoods farm in Bloomsburg, Pennsylvania. Upon further discovering that the purple meteorite contains a purple goop from within, which smells just like a peanut butter and jelly sandwich, then came the discovery that if you eat the purple goop, you start shrinking down to a mere 1/4-inch tall! Years later, when multi-billionaire Dr. Jellystone invites a young elementary school science teacher, Miss Rampling, and her students to be the first ones chosen to visit "Backyard Gardens", his theme park...which is, actually, in his own backyard...so as to (before opening it, eventually, to the public) test the amusement park, THE REAL ADVENTURE BEGINS!!! While Dr. Jellystone assures everyone that the facility's safe, they, during the preview, find out otherwise after a power failure, due to their tour being interrupted by a group of psychopathic terrorists who take over the park, and everyone in it! And its very large insects, in the various kinds, run loose, ferociously, putting everyone's lives in danger, as they're now broken free and going on the hunt! Now, Miss Rampling and her pupils' miniaturized selves face incredible...diminutive, but not really diminutive!...and rampaging dangers, as they venture out, being forced to flee for their lives, and try to make their way to the relative safety of home, by traveling through the dense and perilous jungle-like landscapes of Dr. Jellystone's own now-immense backyard, while Dr. Jellystone fights to search for them in this hostile environment, where nearly everything spells: T-R-O-U-B-L-E! As they're inadvertently becoming embroiled in a hostage situation, can they exit the green maze of thick grass in one piece, while braving running-loose gigantic bugs, a sprinkler, a runaway lawnmower, sadistic extremists, and much, much more
