The inhabitants of Amperville closely resemble Lego minifigures due to the plastic casing that is applied to them, yet they are living, sentient creatures.
The original story deals with the reaction of the larger community when three new citizens are introduced without the casings.
The graphic novel deals with Mr Amperduke begrudgingly taking care of his young grandson, Scampi, one summer.
After a disagreement, Scampi throws a garden vermin, a Nechradon, into Amperville as revenge.
The graphic novel features themes of man's willingness to play God, and the role of science and eugenics (the sophisticate technology used to create and sustain life for Amperduke's simple "hobby") versus Mother Nature (the Nechradon, the unstoppable force that ruins Amperville and ultimately devours its inhabitants).
