This idea started with the post below, but has since evolved into something else. Please go there and share your thoughts.
How cool would it be if we could have tiny glitch doll neopets (sort of like children, but without the messy reproductive and genetic requirements)? They would be autonomous creatures (kind of like piggies / chickens / butterflies) that would be adorable. You could customize their appearance, dress them up, give them little child related tasks (that would generate img, etc.) teach them stuff.
And we could also have a related skill set - parenting (which would mean more predictable behavior in kids and better behaved children), as well as an offshoot of potion making - witchery.
Witchery would be given the ability to craft different potions and spells - advanced spells would involve an enchantment to lure children to that player's home to be used as an ingredient in powerful potions.
If a player can keep their child alive long enough to reach maturity / self-sufficiency, the child will explode in a burst of rainbows and iMG that the parent can then run around and pick up.
