Genpets are advertised online, at a faux web site, that promises allergen-free, child-safe, low-maintenance genetic pets. They look like human-animal hybrids.
“While the Genpets hang on the store shelves they are in a form of hibernation. Each Genpet package has a special nutrient feeding tube attached to it, supplying our specially formulated mix and keeping them healthy and asleep,” according to a Genpets features section.
Review (above quotes) by Treehugger.
I don’t know if pet rocks really want to be dressed up, put into costumes or decorated. Some may feel too dignified for such play. But, I did find pet rock zoo printables (if you need them).
